I don't know how it works on macOS, but on other platforms you can resolve this by either (a) running the client with the --language en commandline switch as per https://syncplay.pl/guide/client/ or (b) delete the .syncplay file in the %HOME% folder (or in Windows the Syncplay.ini file in the %APPDATA% folder). Not sure why German didn't work in the first place though - was there any more debug information?
ahh nice, thanks... i have found an hidden file in my User-Folder :-) /Users/****/.syncplay
i have changed the language back to en. Now it works :-)
hm i have found this in the apple-console: May 6 18:26:17 ****-iMac com.apple.xpc.launchd[1] (pl.syncplay.Syncplay.17036[2757]): Service exited with abnormal code: 255
Ok, I tried to reproduce this on my High Sierra and Sierra machines, so far with no luck. I need further information.
In case you are able to reproduce the crash, it would be great if you could post here a python traceback. To get it, you need to run Syncplay from a terminal. Navigate to the path of Syncplay.app (usually /Applications/Syncplay.app/) and then in Contents/MacOS (so usually, run cd /Applications/Syncplay.app/Contents/MacOS/.
Then run Syncplay by executing ./Syncplay
. Any error message should now cause a traceback log in the terminal window from which you ran Syncplay. Please paste the error message here.
Thanks for your assistance.
Hey,

Thanks, I found and fixed the bug, but many questions arise:
Actually, I found a way to move this further. @Shakal1710 could you please download and install Syncplay from my bintray account? This is the .dmg that contains the fix mentioned above (plus a lot of other new stuff that hopefully will not interfere with this bug). After you installed the updated app, run it from Terminal again and see if you can still reproduce the crash. If so, post here the (hopefully updated) error log. Thanks again.
hey,
the new version is working good! German language is now active :-) no error message.
Great! What happens if you push the "Liste aktualisieren" button in the configuration dialog while Syncplay is set in German?
there comes the message "Konnte die Liste der öffentlichen Server nicht laden. Bitte besuche http://www.syncplay.pl/ [Englisch] mit deinem Browser."
can I ping the server where the list is located? can that be problematic with my port forwarding? which port uses this function?
Well, at the moment I am glad that the error message shows correctly as designed. I will investigate how the server list is updated as soon as I have some spare time. Thanks for your assistance in reproducing this bug.
no problem :)
The update server function loads a URL with several (optional?) parameters: https://syncplay.pl/listpublicservers. This base url should load even with no parameters (afaik). Please check if you can load this URL in your browser.
@Et0h apparently we forgot to edit the "failed-to-load-server-list-error" message and update the url with https:// in all languages. Though this is only a cosmetic issue, I will add a commit to PR #185 about this. I will also add a commit that fixes this unicode bug.
yes, I can load this page
Then something happens in the utils.getListOfPublicServers() function, but you cannot see any error message about it because it is correctly masked by the IOError exception, which triggers the error dialog that you are seeing now. I am not an expert about exceptions in python but, as far as I know, there is no way to skip the exception and get the error message without running Syncplay from its sources and edit the malfunctioning part.
I am still unable to reproduce this part of the issue, given that updating the server lists works for me on High Sierra. If anyone has any suggestions about how to debug this server list retrieval issue on @Shakal1710 machine, please step forward.
@albertosottile I think we could make it check if it is in --debug mode and if so to run the 'raise' command to show the normal stack trace.
@Et0h How should I check if Syncplay is in --debug mode? constants.DEBUG_MODE
apparently is updated only when the configuration dialog is closed. I checked and it is always False before the main window starts.
@albertosottile I think you could add the constants.DEBUG_MODE = config['debug'] to GuiConfiguration.py.
@Shakal1710 I just pushed a fix that shows the update-server-error traceback log when Syncplay is in debug mode. Can you please download and install again Syncplay from my bintray (link)? Then execute it from Terminal, but this time in debug mode, by running
cd /Applications/Syncplay.app/Contents/MacOS/
./Syncplay --debug
Then try again to update the servers. This time a traceback should appear in the Terminal window. Please, paste it here. Thanks again for your assistance.

The "error window" shows "socket error"
When we recently switched entire website to https I have made its SSL configuration very strict. I'm completely unfamiliar with how cert stores and so on work on OSX, but such errors usually mean that there is a mismatch between what precisely is required by SSL server (in this case it is the syncplay.pl web server) and supported in SSL client (ssl.py within syncplay). Technically the certificate itself could be all wrong, but given that it works everywhere else I'd dismiss that option.
I don't know if syncplay on OSX uses operating system framework for SSL, but if it doesn't is it possible that somehow you have old version of openssl or python? Or for some reason it doesn't trust letsencrypt signed certificates?
Just to clarify that update server lists works perfectly in my all macOS 10.12 and 10.13 tests machines, so this is not a general issue, it is just specific to a particular configuration.
Doing some cursory googling with OSX+python+SSL I've discovered that this issue apparently isn't out of the ordinary. Consider this for example.
@Shakal1710 could you post a result of following commands:
openssl version
openssl s_client -showcerts -connect syncplay.pl:443 -strict -servername syncplay.pl
It seems entirely possible that you might have outdated openssl - which will not work with current configuration on web server side.
@daniel-123
openssl version LibreSSL 2.2.7
I have not changed anything in my system.
same version is also on the mac of my girlfriend with the same problem

Hmm, that would make the issue fairly clear. Result of the command confirms that for some reason default openssl implementation used on OSX doesn't have "DST Root CA X3" in its CA store and that this is separate CA store from what the browser uses. This means that not a single letsencrypt certificate will be trusted by python programs on Mac.
As to why @albertosottile doesn't reproduce it - perhaps you have your own, more current openssl (or just certificates) version installed through homebrew? This would explain it working for you. Can you confirm whether it is the same on a default Mac which doesn't have all the dev tools installed?
All that said - there is still one big hole in this hypothesis. How in the world does this break only if you select German language? This would imply different certificates trusted depending on language settings, which seems utterly insane to me, but I cannot test it as I don't have a Mac. Could either of you test result of the openssl test from before with different operating system language settigns?
@daniel-123 homebrew openssl by default is keg-only, so it does not overwrite macOS default version. However, I do not think that our bundled .dmg uses system-wide openssl libraries since those are quite old. As a confirmation, here there are the results of the commands you asked, ran on my macOS 10.12 laptop (sorry, but is the only one I have available for the next two weeks).
which openssl
/usr/bin/openssl
openssl version
OpenSSL 0.9.8zh 14 Jan 2016
openssl s_client -showcerts -connect syncplay.pl:443 -strict -servername syncplay.pl
unknown option -strict
Given that the bundle includes a libssl and a libcrypto, I am quite convinced that Syncplay uses its own ssl libraries. But, for some reason, they are not working on @Shakal1710 machine.
@Shakal1710 Your openssl version string looks quite weird, perhaps you installed a different version of openssl in your system somehow. Can you post the result of which openssl
here? Also, knowing your full $PATH by running echo $PATH
could be nice. Thanks.
hey, I have not changed anything on the system...
the "retrieve the list of public servers" failure is available in all languages
Philips-iMac:~ philip$ which openssl
/usr/bin/openssl
Philips-iMac:~ philip$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin
I'll try it on a MacBook Pro early 2015 with clean install. (I wanted to sell it anyway)
edit: new install of High Sierra (10.13.4) on my MacBook Pro: Same open ssl Version (LibreSSL 2.2.7) and same problem with loading the public serverlist
Then I will have to check the output ofopenssl version
in my 10.13.4 setup, but unfortunately that will not be possible for the next two weeks :/ I tested server list retrieval and it worked, though. If anyone else with that macOS version can test updating server list and post the results of those commands before, that would be great.
Edit: Apple switched to LibreSSL in HIgh Sierra, so that string is probably normal.
@Shakal1710 Sorry if I disappeared, now I am back. Can you please download an updated version of Syncplay from my bintray (link), install it, run it again in debug mode as described before, and attempt to update the server list? Please paste here the error message, if any. Once again, thanks for your help.
Ok, I will test it later this day :)
sorry for late answer :(

The traceback still strongly points to SSL outside Syncplay being the direct culprit. This is further supported by previous result of openssl s_client -showcerts -connect syncplay.pl:443 -servername syncplay.pl
command, which has the line verify error:num=20:unable to get local issuer certificate
in it - as I previously mentioned this means that openssl didn't find the DST Root CA X3 root certificate in the cert store it is using.
There are still some things that aren't clear to me:
openssl s_client -showcerts -connect syncplay.pl:443 -servername syncplay.pl
for different domains? github.com, google.com and letsencrypt.org for example.As far as understanding and remedying the issue goes, it depends on why exactly that root cert is missing:
openssl s_client -showcerts -connect syncplay.pl:443 -servername syncplay.pl
command on a fresh installation of MacOS.Its in all languages!! changing region and language in MacOS from German to USA/english dosn't help
openssl s_client -showcerts -connect github.com:443 -servername github.com

its also broken on the Mac from my girlfriend. its also corrupt? hmmm
Okay, output of those commands says that openssl doesn't trust any of those three certificates. I'd like to assume that this is the default behavior (since you have 2 machines on which this works the same way) - but then this means that the openssl cert store provided by Apple is completely broken (or outright missing). Though in that light it is weird how:
EDIT: I am digging in the py2app bundle, even though we are embedding all crypto libraries, the bundler does not embed a copy of bin/openssl and uses the one that is available on the system. So, @daniel-123 you were right, I am sorry. Thus, we need to fix the server configuration to make it work with system openssl on vanilla macOS without homebrew. At this moment, from 10.12.6 for example, I get this:
~ alberto$ openssl version
OpenSSL 0.9.8zh 14 Jan 2016
~ alberto$ openssl s_client -showcerts -connect syncplay.pl:443 -servername syncplay.pl
CONNECTED(00000003)
28437:error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version:/BuildRoot/Library/Caches/com.apple.xbs/Sources/OpenSSL098/OpenSSL098-64.50.7/src/ssl/s23_clnt.c:593:
Trying to find more info on this issue online I found this: https://github.com/requests/requests/issues/2955#issuecomment-222098821 Which certificate are we currently serving on syncplay.pl?
@albertosottile you can see the certificate within browser when visiting syncplay.pl website or put it through SSL Labs Test. SSL configuration on webserver is indeed incompatible with OpenSSL 0.9.8zh, as that is positively ancient version with no support for modern encryption (it doesn't even get to the point where it checks whether the certificate is valid). I'll investigate whether it is possible to configure SSL in a way that is both working with 0.9.8zh and not vulnerable to any of the known exploits (otherwise - http fallback is just as good).
That said - your protocol mismatch is completely different issue from what @Shakal1710 is seeing. His OpenSSL implementation is actually compatible with what the webserver is set to. It is just that it considers the certificate itself to be invalid - but given that it also thinks Google and Github certificates are untrusted I cannot really imagine how his OpenSSL (LibreSSL 2.2.7) is working correctly. I also don't understand why it is different from yours.
Edit: I've took a look at the requests issue you linked - it describes a site that doesn't serve intermediate cert. syncplay.pl does serve the expected intermediate cert - you can see it results of sample ssl connections all over this thread - there always are 2 blocks containing certificates: one for leaf and one for intermediate certs.
@daniel-123 The error log I reported before is relative to macOS 10.12, while those reported by @Shakal1710 refer to macOS 10.13, which embeds LibreSSL 2.2.7. On my 10.13 test machine, I get exactly the same results as him, yet the update function works because Syncplay is able to fallback on the homebrew openssl binary.
As far as I know, a viable and quicker solution for both systems could be to switch this getListOfPublicServers function from urllib to Requests. As a mere example, the code of the try part of the function could be replaced by:
import requests, syncplay, sys, messages
params = {'version': syncplay.version, 'milestone': syncplay.milestone, 'release_number': syncplay.release_number, 'language': messages.messages["CURRENT"]}
resp = requests.post(constants.SYNCPLAY_PUBLIC_SERVER_LIST_URL, data=params)
response = resp.text
response = response.replace("<p>","").replace("</p>","").replace("<br />","").replace("“","'").replace("”","'").replace(":’","'").replace("’","'").replace("′","'").replace("\n","").replace("\r","") # Fix Wordpress
response = ast.literal_eval(response)
Just tried this code on my macOS 10.13 machine using system python (not homebrew) and got
>>> response
[[u'syncplay.pl:8995 (France)', u'syncplay.pl:8995'], [u'syncplay.pl:8996 (France)', u'syncplay.pl:8996'], [u'syncplay.pl:8997 (France)', u'syncplay.pl:8997'], [u'syncplay.pl:8998 (France)', u'syncplay.pl:8998'], [u'syncplay.pl:8999 (France)', u'syncplay.pl:8999']]
while
>>> import ssl
>>> ssl.OPENSSL_VERSION
'LibreSSL 2.2.7'
So, in theory, this modification should work on vanilla macOS 10.13 installations. @daniel-123 Do you think this code is fine enough to put it in a Syncplay .dmg and make it test to @Shakal1710 ?
Ok so, apparently embedding Requests with py2exe is a nightmare and, after all, urllib seems to work on Windows so far. Thus, I see no reason to mess with code that works and I restricted the use and packaging of Requests to macOS only. @Shakal1710 can you please, once again, download and install the latest build from my bintray (link) and test it again as before? Hope this is the right one.
now its working!!! :-) now I see the 5 servers in the list
I can not post anything because there are no errors in the terminal window :-)
@Shakal1710 Can you also verify that manually checking for updates works? Open Syncplay, store the configuration and run it, then from the menu bar go to the 'Help' menu and click 'Check for update'. No need to run Syncplay in debug mode. Thanks.
@albertosottile a small update as I've done some digging into how SSL in python is handled on OSX. Or rather - how by default there literally is no cert store so it simply will not work without additional steps. Requests apparently bundles its own cert store, which explains why it works.
In the end the missing piece that should be relatively easiest to integrate seems to actually be Certifi. I'm not sure if anything more than simply packaging it along with Syncplay is needed (as I don't have a clue how .dmg files work).
Certifi is already embedded with Requests. I tried to embed only Certify but it did not was enough for example for macOS 10.12, in which the default OpenSSL version is too old to support the profile of syncplay.pl. With Requests, everything works without homebrew on macOS 10.11+ .
@albertosottile the manual update check says there is a newer version available. than I can visit the website
Ok, disregard the message about a newer version, I just wanted to check if your system could contact the server also in that function (if you want the correct message 'Syncplay is up to date' you can always download the latest build from my bintray, but that is not necessary). So, this issue appears to be fixed now, thanks for your assistance. I included the fix in the PR #185 , I will close this issue after the merge.
Thanks to everyone for your work in helping to fix this issue.
Hello, I changed the language from English to German. After a restart of syncplay the following error occurs:
can I change the language back manually in a file or something else?
OS: MacOS High Sierra 10.13.4 syncplay: last (1.5.3a)
edit: deleting and reinstall of syncplay do not change anything
