MinimWatch on MX Linux

[simoncn]

MinimServer uses port 9791 for communications from MinimWatch. MinimWatch also creates local port numbers dynamically for inbound communications from MinimServer.

As a start, you could try opening port 9791 in the firewall for outbound connections. If this doesn't solve the problem, it is likely to be caused by inbound connections being blocked by the firewall.

Are you able to configure the firewall to allow inbound connections to the MinimWatch process on all port numbers? This is how it works when running MinimWatch on Windows.
