I couldn’t get Plex remote streaming to work until I made this simple fix

Plex remote streaming commonly fails because the home server isn't exposed to the internet. The fix is port forwarding on port 32400, combined with assigning a static internal IP to the Plex server via the router's MAC address reservation. Additional troubleshooting tips include checking account login, enabling secure connections, disabling VPNs that may block incoming traffic, and ensuring the server stays powered on and connected.
