If Remote Access is enabled and PMS shows “Not available…”, then your Plex server has not successfully registered with the hosts at plex.tv.
When enabling remote access, PMS initially shows green. This is the server trying to register with hosts at plex.tv. If the registration fails, it will revert to red with the “not available…” message.
In Settings => Remote Access, the Manually Specify Public Port checkbox tells Plex Media Server to use either manual port forwarding or UPnP.
If you use manual port forwarding, you must check the box to manually specify a public port.
If you use UPnP, do not check the “manually specify” public port.
You can use either manual port forwarding or UPnP. If using manual port forwarding, you can leave UPnP enabled on the router for use by other services / devices.
See screenshots below from my Asus router and Plex remote access configuration.
Additional Troubleshooting
Login to your Asus router. Look at the WAN IP on the Network Map page.
- It should match the Public IP shown in Settings → Remote Access. If it does not, then remote access will not work.
- If it is a RFC-1918 reserved address, then you are likely in a double-NAT situation and Plex remote access will not work.
RFC 1918 addresses: 10.x.x.x; 172.16.x.x to 172.31.x.x; 192.168.x.x
You can verify if your port is open via canyouseeme.org.
- Plex Media Server must be running with remote access enabled.
- From a system on the same network as your Plex server, go to https://canyouseeme.org.
Your IP should match the IP address displayed in Plex remote access settings.
If it does not, then the test will fail.
- Set
Port to Check with the Plex remote access port.
- Click
Check Port.
If the site can see your server it will return a Success message.
