I'm traveling to my parent's soon and I need everything to be working before I'm gone so I can remotely manage my PC.
The problem is that I can remotely connect to some services, but not others. For example, Plex, Emby and TeamViewer work. I guess programs that do their own thing with ports have no problems. Programs where I have to manually specify ports and do the forwarding don't work, like NZBGet, Sonarr and Couchpotato. Ports are forwarded correctly in the router and as far as I can tell I don't think there's anything incorrect in Windows 10's firewall. Just a few minutes ago Plex wasn't working until I disabled manually specifying the port used and it miraculously worked. I'm honestly out of ideas.
Any help is appreciated.
Edit: I should note, everything was working fine some months ago but I have no idea what changed.
