Can't connect Barrier from Ubuntu 22.04 to Windows 10

I have installed Barrier(v. 2.4) for both Ubuntu and Windows. Keeping the Ubuntu PC as server and the Windows as client (or vice-versa), I've been unable to establish a connection. Server Logs (Ubuntu machine are as follows):

[2022-05-23T19:41:16] INFO: starting server[2022-05-23T19:41:16] INFO: config file: /tmp/Barrier.iSqQUR[2022-05-23T19:41:16] INFO: log level: INFOstarted server (IPv4/IPv6), waiting for clients

Whereas on the client side(Windows 10), following logs are there:

WARNING: failed to connect to server: Timed out

I've also tried to disabled the firewall as well as disabled the SSL from Barrier but nothing seems to work. Any help would be much appreciated.
