@girish many thanks for the advice I did as you asked and I could not telnet to the server via the terminal app, so I then went to the cloudron server and tried it from there it would also not work, which lead me down a bit of rabbit hole 😄
Eventually I managed to find and issue with the virtual nic on the server itself and managed to resolve that, and now it is working perfectly.
Not sure how I missed it but you helped me find so many thanks.
Kind Regards
Scott
