Originally created by @Cubytus on GitHub (Apr 21, 2022).
Original GitHub issue: https://github.com/debauchee/barrier/issues/1651

What happened?

On each start, Barrier on the server computer repeatedly asks whether I want to allow incoming connections (first problem).

Then, on trying to start Barrier, it doesn't succeed but throws the same error lines in the log (second problem)

Server settings:

SSL is disabled since it tends to cause problems.

During that time, no client Barrier can connect as they detect a "Connection refused".

Version

v2.4.0

Git commit hash (if applicable)

No response

If applicable, where did you install Barrier from?

From here.

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

macOS

What OS versions are you using?

Server is Mac OS X 10.14.6 Mojave.
Clients are Windows 10 and Mac OS X 10.13.6

Relevant log output

Any other information

These log lines are endlessly repeated until I quit Barrier.
I tried to fully erase Barrier using AppCleaner, to no avail.

Was having the same issue today. What resolved it for me was uninstalling Barrier on the Windows device and re-installing.

Rename the screen name in the server config to: Lancelog-Mo.local
