Original GitHub issue: https://github.com/debauchee/barrier/issues/1281

What happened?

Barrier worked perfectly for me until we switched IT systems at work, and I no longer have administrator rights. I am therefore assuming that this is the issue, however I am hoping that someone has a fix or workaround.

I am connecting a Windows machine with a machine running Ubuntu 18.04.
I am manually inserting the server IP, and have tried to connect both with and without SSL enabled.
The server is not configured in any way, except for placing the two computers on the interactive grid. Again, this worked fine before the IT change.

Version

v2.3.3

Git commit hash (if applicable)

No response

If applicable, where did you install Barrier from?

The Ubuntu version was installed with snap, using the command sudo snap install barrier

The Windows version was installed with the 2.3.3.exe release

What OSes are you seeing the problem on? (Check all that apply)

Linux, Windows

What OS versions are you using?

Windows 10, Ubuntu 18.04

Can you please run CMD.exe on your server and do a ping and a traceroute to your client? (tracert ip-of-client)
And also do the same but the other way around from your client? (traceroute ip-of-server) and post results?

I would like to test if both clients can even reach each other.

Hello,
Apologies - I was simply an idiot, who didn't notice that during the IT change, the network was also changed for one computer, but not the other. Switching to the same network fixed it for me facepalm
