Original GitHub issue: https://github.com/debauchee/barrier/issues/684

Operating Systems

Server: Linux Mint 19
Client: Windows 10

Barrier Version

2.3.2

Steps to reproduce bug

1- open barrier on linux, start as server and the windows 10, claims with connection refuse. Its try to connect to 192.168.0.26:24800 (linux server)
2- in linux server, get the listen tcp port:

the process running was:
/usr/bin/barriers -f --no-tray --debug INFO --name ant1-MS-7A70 --enable-crypto -c /tmp/Barrier.TJ4947 --address :24800

There's no tcpv4 listen port. To solves, need to explicit the binding tcp v4 ip .... change the barrier config and lunch as:
/usr/bin/barriers -f --no-tray --debug INFO --name ant1-MS-7A70 --enable-crypto -c /homne/ant1/barrier.conf --address 0.0.0.0:24800

the change was , and then, the listening port with tcp v4 its ok.

the barrier client immeadiatle connect the the server with success at the first try.

theres another way to change the binding ip? Every server reboot, need to stop de barrier startup and the lunch manually the new script.

Best regads!
