Error "Failed to connect to the server: Timed Out", on Barrier

I have a machine with windows and one with Linux Ubuntu.

I'm trying to make the connection between both, using Barrier (a software that connects two machines so I can use the same mouse and keyboard on both).

I'm using Windows as Server and Linux as Client. But when I start, I can see the following WARNING message in the Client log on Linux.

"WARNING: failed to connect to server: timed out"

Note: When I use Linux for Server and Windows for Client it works.

Already tried:

-Disable Windows Firewall;

-Disable SSL on both Barries;

-I already uncommented #WaylandEnable=false.
