Even though I can enable the port and supposedly access it remotely (so it says) I cannot accesss ANY other shared servers, I cannot access any content from external sources (mobile/tv/webapp).
port fowarded fine, tried other ports, exposed entire host without any issues canyouseeme confirms port is open correctly.
disable and renable remote access works for 10 seconds and kicks out
changed ports(32400 private to 32401 public), server ip(within same subnet), dns(fallback to public quad1) and all I could(googling upnp settings etc) and still the same issue.
accessing via ddns works… for local server only but no video playback is working, only metadata etc.
turns out somehow over last day, plex changed how they handle cookies (don't see any statement from them) but privacy badger managed to block all of them which looked like rand with leading private ip addresses, once allowed or disabled for site, started all working again.
