Windows client not able to connect to specific port

In one computer with version 3.4 I am able to specify the server port when setting URL. For instante:
But in a different computer I just installed the client (which is 3.6.4) and it is not working anymore. when setting the url with the port like above, it opens the browser but it writes URL without the port, so it is not working. When manually changing in the browser the url to add the port, I connect, but client doesn’t connect because port is missing in client configuration.
Is this a bug? Or a feature removed?

Thanks and BR

Just try it with an older version to verify, whether it may be a bug or not.
If it works with version 3.4 on a different computer, downgrade the 3.6.4 version to 3.4.
