I upgraded to V 0.04 to get access to my Start9 Server from outside my home network. I followed all instructions for Start Tunnel with my IONOS VPN and external connection worked great with no issues. I am now away from my home network for about a month and connection is not working. I checked my IONOS VPN and it is green and UDP 51820 is identified as open. I do not know where to start trouble shooting. Can connection be fixed while I am away from home network?
