Steps to reproduce problem:

Other info

The problem started after a fresh install on both machines.
So far i've found no workaround, only that the same happens when both machines use windows.
The bug prevents me from using the software.
I tried running with firewall off and SSL turned off, problem persisted.

@Ds886 commented on GitHub (Nov 12, 2020):

Make sure the alias is properly fitting what the client tell

for example on the server as linux it says
WARNING: unrecognised client name "roni-laptop", check server config [2020-11-12T19:29:52] NOTE: disconnecting client "roni-laptop"

so adding an alias on the server to the client "roni-laptop" should remove this limitation

Check connectivty.
you can easily check it on windows using the powershell command
tnc -port

or on Linux using:
telnet , (not sure about the syntax)

check ports are forwarded properly.
On windows Windows Firewall will block by default most ports from outside to inside.

Well, this is embarrassing and awkward and everything horrible, because i just realized it was not a bug. Turns out there was a menu i wasn't aware of existing, terribly sorry for wasting your time.

Should mention that after adding the screen name, you must reload Barrier if it has already been started.
