Some items to check:

Leave the VPN disconnected/disabled for an extended period of time, to ensure it is not interfering with Plex remote access.

Configuring port forwarding with a BGW320: Changed ISP - No Remote Access with AT&T BGW 320-500 - #3 by FordGuy61

Have only one network connection on the Plex server active. If the PC also has a Wi-Fi interface, then disable it.

Ensure the Ethernet port is Private, not Public. Settings → Network & Internet → Properties.

Ensure the PC cannot power down the Ethernet port to save power.

  • In the Taskbar search box, enter Network Connections to bring up the control panel.
  • Right click on the Ethernet interface & choose Properties.
  • In the Properties window choose Configure → Power Management
  • Uncheck “Allow the computer to turn off…” and OK to save.

Use Tautulli or a service such as Uptime Robot (free) to notify you when remote access is not available (have Uptime Robot monitor the public IP address & port of your Plex server).
