GSConnect can't find my android phone

ghost commented 2 years ago

GSConnect can't see any device on any network. I have other Android devices that can see each other but GSConnect can't see any of them and they can't see GSConnect. I tried adding the IP manually it still didn't work.

Steps To Reproduce:

Go to Settings
Click on refresh'

Expected behavior Devices on my network should should show up

I'm at the same place.

My initial suspicion would be firewall issues, the wiki "Common Problems" section has some info and links on how to open firewall ports.

For auto-discovery GSConnect needs to be listening for UDP messages on port 1716, and that port needs to permit incoming datagrams from the network.

You can check whether a device is discoverable using netcat; if your phone's IP is 192.168.1.2:

You can also do the same thing to localhost, just to check that GSConnect is listening, though this can't tell you whether a firewall is blocking connections from other machines.

In either case, the "Connection to _____ 1716 port [tcp/xmsg] succeeded!" message is the one you're looking for.

(If you have a second Linux machine on the same local network, you can run that netcat command to its IP address to check whether your firewall is blocking the connection.)

If you have a shell-console app like ConnectBot installed on Android, it does have a very primitive netcat command that can be used as well:

If your Linux system's IP is 192.168.1.3:

:/ $ # A failed connection attempt will error out immediately...
:/ $ netcat -t -W 1 192.168.1.3 1716
netcat: connect: No route to host
:/ $ 

:/ $ # If it succeeds, it will pause for 1 second and then return the shell prompt:
:/ $ netcat -t -W 1 192.168.1.3 1716
:/ $

Ugh, sorry. Those last commands should read...

:/ $ # A failed connection attempt will error out immediately...
:/ $ netcat -t -W 1 192.168.1.3 1716
netcat: connect: No route to host
:/ $ 

:/ $ # If it succeeds, it will pause for 1 second and then return the shell prompt:

iw00d commented 1 year ago

I'm not frequent enough at Ubuntu computers to know what I did to fix it. But when I couldn't find the running process, I ended up installing KDE Connect from the Ubuntu Software APT. If having this extension worked, IDK. If that's what I'm supposed to do, IDK. By the time I finally got connected, I had lost where I got the tip to use this extension. So I ended up installing Dolphin and really making a mess out of my fathers computer. The next time I see him, I'll try to figure out what I did and probably give up fixing that. But I managed to get the files from his phone through TeamViewer, and that's whats important.

So there, future person. Read the link I provided above unlike what I did, throw more files at the problem or read the documentation.

Well, if you managed to achieve what you needed to do, that's what really matters. But for the sake of those future bug-readers, I will say: Installing KDE Connect (the Linux part) is definitely not a solution to anything involving GSConnect. In fact, having kdeconnectd running will unequivocally BREAK GSConnect. You most assuredly do not want to do that, to address this problem.

That bit's even covered in the troubleshooting FAQ.

(The issue is that KDE Connect, the protocol, operates over a fixed set of network ports. If kdeconnectd has attached itself to those ports, then GSConnect cannot. It's the same reason you can't have two instances of GSConnect running on the same system, even as different users.)

NeuHix commented 1 year ago

Yesterday, I tried all the soultions in the the wiki "Common Problems" section And today morning, GSConnect started working on its own. And it is still working currently.

bevsxyz commented 1 year ago

I think for here, the issue is openssl system package. Make sure you have it installed. The wiki mentions it for Fedora Silverblue https://github.com/GSConnect/gnome-shell-extension-gsconnect/wiki/Help#openssl-not-found However, it is possible for you to have the issue with other distros as well.

With fedora, you could further try ensuring that the kdeconnect service is allowed in the firewall. https://github.com/GSConnect/gnome-shell-extension-gsconnect/wiki/Help#cli I just tested these two couple of hours ago in Fedora. For other distros, you'll have to check with your firewall manager.
