Remote access suddenly stopped working

Server Version#: 1.18.5.2309-f5213a238
Player Version#: 4.59.2

I’m running Plex Media Server on my Synology NAS (with DSM 6), and it has been working fine for several months. Two weeks ago, however, my house lost power while I was out of town, and ever since returning from that trip and turning the NAS back on, Plex has been “not reachable from outside your network.” I did not change any of my settings, and I have tried rebooting both the NAS and my router several times, so I don’t see any reason why remote access would suddenly stop working like this.

My Plex server is configured to manually specify a public port (32400), and I have configured my router (an Asus RT-AX56U) to manually forward this port to port 32400 on the NAS’s internal IP address. I have disabled UPnP on the router, just in case, though it didn’t change anything. The router is also configured to assign the NAS a fixed IP of 192.168.50.90 instead of using DCHP for it.

When I click “Retry” on the Remote Access settings page, I notice that after waiting for a few seconds, the page very briefly flashes the “Fully accessible outside your network” message before changing to “Not available outside your network” and changing the green arrow between “Public IP” and “Internet” to a red X. I wonder if the fact that it seems to work for a second before breaking indicates that something within PMS crashed after making the connection to the Internet.

I’ve attached a log folder that I downloaded shortly after one of my attempts to reconnect remote access. I hope someone is able to figure out what’s going wrong so that I can fix it and get my remote access back.

Saw your comment in the other thread. These logs don’t help. I need the log from after PMS starts.

  • restart PMS
  • wait 3 minutes without doing anything
  • grab logs

Thanks for the responses. I didn’t realize the logs I had posted weren’t helpful, but I’m happy to follow directions to capture them in a better way. Here are the logs I downloaded after restarting the PMS process and waiting a few minutes without doing anything:

I’ll also start working on manually installing PMS from the ARMv8 package, and see if that fixes the problem.

I manually updated the Plex package on my NAS following your directions, rebooted the device, and Remote Access seems to be working again. In the future I’ll avoid trusting the Synology package manager and update PMS myself.

Regarding the media folders, I had no idea that I wasn’t supposed to use the pre-existing “music” and “photo” folders; I wish I’d found that how-to page when I was first installing Plex on my NAS. If I want to “migrate” my existing Music library to a new folder (e.g. /volume1/PlexMusic/) without re-indexing everything, I’m guessing I should use the process described here?

OK, I followed these steps and the Plex server has successfully found my libraries in the new folders. Thanks for the help.
