Serviio Pro remote access failure
I moved a perfectly working system from one location to another and back again. In the new location, it worked flawlessly after setting up port forwarding (with a Ubee modem). I moved it back to the original location, restored the original static IP (which is also bound to a URL in DNS) in Serviio console, and now, for some reason, remote access fails! Note that local access via the local network IP is fine.
To be clear: port forwarding is still in place on the original modem. The local network has not changed at all.
How to troubleshoot this problem? Will stopping the Serviio process and restarting help? Rebooting the cable modem? I am out of ideas.
