I found that I was having difficulty getting the remote connection reestablished after upgrading to the 1.0.0.2261 release for PMS.
Note: This only works for UPnP capable routers.
What I ended up doing was:
- Disable remote access under the PMS server settings
- Open my router firewall page and remove all of the rules added by the plex server.
- Enable remote access under the PMS server settings.
- Wait 5 minutes for route tables to update
After this it worked fine.
May work for you or it may not but it’s worth a try.
