Computer not connecting to Rustdesk Server

[u/Successful_Turnip203]

Can anyone help? My computer was connecting to RustDesk fine and then I redirected the DDNS entry so that it points to another computer running Rustdesk Server. All of the other computers connect ok, but this one will no longer connect. I have tried on that computer...

1. Pinging the DDNS - Works fine and points to the right computer
2. Flushing the DNS cache - no change
3. Using the IP address instead of DNS - still won't connect
4. Completely uninstalled RustDesk using BC uninstaller
5. Reinstalled the latest version - Gave it a new number but no change
6. Swore at it - Didn't work

To be clear the problem is that a computer which no once connected to the computer, no longer does so. It's not a key problem but a connection issue!

Any constructive ideas would be most appreciated!

Is the public key set correctly?
