I have a question about port forwarding. I am running Plex on Debian 12 bookworm and my remote access stopped working for some reason. I have spent the last couple of days trying to set up a VPN and was successful yesterday getting it to work. I currently have it turned off but remote access still doesn’t work. I have attempted to use port forwarding and did manage to get it working but it works for a minute and then becomes inaccessible. I have used a single port as well as using a range of ports. They always initially connect and then drops out after a few seconds. Any idea where my problem might be?
