Collabora Online failes to load, when file is share by public link. No errors logged.

[BjoKaSH]

Describe the bug Collabora Online fails to load with message "Failed to load Collabora Online - please try again later" when a user (not logged in) tries to access the file by password protected public share link. The messages appears a few seconds after the dialogue box "Select your Nickname" has appeared. The dialogue box disappears when the messages is shown.

If one is quick enough, one can manage to type a name in the dialogue box and hit enter before the messages appears. Then the pages reloads, but ultimately fails with the same "Failed to load Collabora Online - please try again later".

If one now manually reloads the page, then the document opens in Collabora Online as expected.

For a shared by link file, this "quickly type something in the 'nickname' box, hit enter, wait for error, reload" seems to be the only way to open a file in Collabora online.

For logged-in users, no problem exists, Collabora Online just works as expected.

To Reproduce Steps to reproduce the behaviour:

1. create an empty folder in NC
2. upload or create an office document (example here: a LibreOffice Calc document)
3. share the file (not the folder!) by link: Set a password, enable editing, disable download. Note down / copy the link
4. log out. Make sure the NC really don't remember you.
5. Try to access the link
6. NC will ask for the set password, provide it
7. NC will start loading, showing a "select your nickname" dialogue after a few seconds
8. do nothing. do not enter a nickname
9. After several seconds, the dialogue disappears and a message "Failed to load Collabora Online - please try again later" is briefly shown. Page turns empty (not counting the standard footer)
10. Try reloading the page (remove the automatically added ?# from the URL before), steps 7 - 9 will repeat. Try several times, if you like.
11. Try reloading the page, but quickly click the "select nickname" box as soon as it appears, type a character and hit enter. You have (on my box) approx. 3 seconds to do so.
12. A new page will load, but stay empty. After some seconds a message "Failed to load Collabora Online - please try again later" is briefly shown.
13. Try reloading the page. The document opens as expected.

Expected behavior

1. User clicks shared link
2. NC ask for password
3. NC ask for nickname
4. Document loads

One more detail: I tried to find the last working version by bisecting versions from 2.0.10 to 3.4.1. Last working version of richdocuments app is v3.3.12. Version v3.3.13 does not work.

Within version v3.3.13 the last working commit is 8bc4166 (Do not reload files list on initial load), first non-working is ea430b5 (Remove additional check call and show error if no collabora loaded after 15s). However, it is no clear to me, if the added timeout check just reveals an other problem, or if the logic behind the test is in itself broken.

If I find time, I'll try to investigate a bit deeper next weekend.

Having the exact same issue here. I share a link for editing with no password set on it. Still happens on NC17 and I do see an error in the logs:

I have the same issue. On public link to some users it does not work - but if they use anonymous browser window, it works great. I think there is some collision between public link and logged user session.

However, for me as creator of the link (and logged user) it works fine. For the others - they need to open public link in an anonymous browser window.

The log says in such case: Undefined index: userId at \/www\/nextcloud\/apps\/richdocuments\/templates\/documents.php#8

To some users it started to work when I patched documents.php:

In 3.4.3 the problem is still here. I focused on cookies because in anonymous browser window the error does not exist. Maybe it helps @juliushaertl

1. as logged regular user I have two cookies: nc_session_id and <instanceid> (instanceid as in config.php) both containing the same value (let's say XXX). The document on public link does not load, ending with error.

2. if I log out regular user, the nc_session_id cookies disappears and the cookie <instanceid> contains different value (let's say YYY). Now the document on public link works.

3. However, if I am logged as in the 1st example and simply delete nc_session_id cookie and leaving <instanceid> with XXX (value of logged user) - the document does not loads.

4. If I delete <instanceid> only, it also does not work - a cookie with the same name and value of XXX appears after reload.

The problem does not exist on the public link I create and try to use. I guess the XXX value of the logged user (or valid session) somehow interfere with user id owning the shared file?

In 3.4.3 the problem is still here. I focused on cookies because in anonymous browser window the error does not exist

@vpecinka Any change you could try 3.4.4? I could not reproduce the issue neither with or without being logged in. Maybe you can share the error message to the error you mention in richdocuments/lib/Controller/WopiController.php#609

[vpecinka]

I will try it in the evening. Did you try to load file provided by someone else? If you try to access file via public link you created itself, it works. But not if created by someone else.

In 3.4.3 I got no error in nextcloud.log file, it has been mitigated. The rich document app still says (in Czech, so no exact phrase in English :): Cannot load the document. Please contact the administrator of your storage.

I caught the following error on LOOL side: (sensitive info removed, however in the uri is my logged username nc_username, so probably other parameters are also valid for logged user):

@vpecinka Any change you could try 3.4.4? I could not reproduce the issue neither with or without being logged in. Maybe you can share the error message to the error you mention in richdocuments/lib/Controller/WopiController.php#609

Tried 3.4.4, still not working. Reproducible steps:

1. logged as user A create public link (editing allowed) and copy that link to clipboard
2. log out and log in as user B
3. enter public link from step 1 to the browser
4. error occurs
5. log out user B and enter public link again
6. everything works well

Tried also NC 16.0.6 + rich documents 3.4.4, storage is Swift.

We are experiencing the same issue, on our production server and test server with Nextcloud 16.0.5 and rich documents 3.4.4, using local storage.

Happy to test any solutions or ideas on this.

[vpecinka]

I also noticed, that in the top menu bar, where currently cooperating users on one particular document are displayed, there is mix of different users from different documents.

I shared a document X to the user A via public link - user opened the document. I also opened the document, but directly from my storage. Then I left and opened another document Y. However, I can see the user A among the participating users (the LOOL admin console says that he is not viewing that file Y as well).

https://github.com/nextcloud/richdocuments/pull/700 Should fix this. Testing is very welcome.

700 Should fix this. Testing is very welcome.

I applied patch to my running 3.4.4 version and works great! Thanks @juliushaertl

Hi, this issue is back when I upgraded to NC 17.0.3 with richdocuments 3.5.2

Steps to reproduce

1. login as an user, create public link to a office file
2. logout such a user and log in as another one and keep logged in
3. use the public link

The document cannot be loaded, in the nextcloud's log is nothing but HTTP 403 is returned:

10.75.139.137 - - [05/Feb/2020:10:45:38 +0100] "GET /index.php/apps/richdocuments/wopi/files/32693_<sensitive>?access_token=<sensitive>&access_token_ttl=0 HTTP/1.0" 403 2 "-" "LOOLWSD WOPI Agent 4.2.0" "-"

When logged out completely or logged in as the owner of the file under public link, it works.

[vpecinka]

For complete context - I upgraded from 16.0.6 to 17.0.3

[juliusknorr]

Hm, too bad, thanks for reporting. I'll look into it

[vpecinka]

I think here:

https://github.com/nextcloud/richdocuments/blob/bbc3a31a30bcd482f6fe86a1167393ef1e4e19dc/lib/Controller/WopiController.php#L660

should be $userFolder = $this->rootFolder->getUserFolder($wopi->getOwnerUid()); as under public link we need to access owners folder(?)

Or the guest detection doesn't work properly, as

var_dump($wopi->getGuestDisplayname());
echo("\n");
var_dump($wopi->isGuest());

gets in my case

NULL

bool(false)

Maybe there can be guests with no nickname (at least I'm not asked to enter guest name).

This is still an issue with:

• Nextcloud 20.0.8
• richdocuments 3.7.17

Any progress here?

[eBug]

This is also an issue with NC 23.0.0 and Collabora Office 6.4-50 (git hash: d53ee72), when I share a public link to a folder, anonymous users can't create or edit documents online.

[quentinDupont]

@eBug it's the same issue here : https://github.com/nextcloud/richdocuments/issues/1914
