Lost External V0.04 Connection to Start9 Server

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?

If you have full access to your VPS, with StartTunnel running, that’s the obvious place to start. SSH in and try to pin your server on the VLAN IP, 10.x.x.2
