I am using a Pi 4, Bookworm and wfview 2.11 as client for a remote setup.
Formerly DX Cluster worked nicely, but no longer, it can not connect to the cluster server.
But telnet works from the Pi with command telnet dxspider.co.uk 7300, after contact and supplying my call as user.
It does not seem to matter if I have a port forward rule or not for the PI. Port 7300 is not open on the Pi when scanning for it.
Any idea what can be wrong?
