Lost server after network reset

I had to factory reset my router and neglected to copy over my port forwarding rules. I went into plex and was checking secured connection but somehow in the process of this it locked me out - I have no access to my NAS files. Now in my Plex settings it says that my server is unavailable along with the message “Unable to connect to “SERVER” securely.” I cannot access the secured connections setting, so I can’t adjust it in any way. Do I need to uninstall / reinstall plex with the Keep/Token options?

Server Version#:DSM 7.1.1-42962 Update 6
Player Version#:1.32.5.7349-7000
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Plex Media Server must be able to communicate with hosts at plex.tv for the claiming process to work.
Make sure the NAS can communicate with devices on the Internet.
Simple test of DNS & communications:

  1. DSM Control Panel → Regional Options → Time
  2. Synchronize the NAS with a NTP server such as pool.ntp.org.
  3. If successful, it will return “Successfully synchronized with server_name.”

Uninstall Plex Media Server with the “Uninstall Only” (first) option.

Re-install the same version with the Plex Claim Token option.
If successful, you will see “PlexMediaServer successfully claimed by “username”.”

Connect to PMS using the IP address of the server: http://syno_ip_address:32400/web.
You should be able to login and reach server settings.
Then try using https://app.plex.tv/desktop/.

Thank you, Ford, I did this but am right back where I started. Confirmed that NAS is able to access internet via time and uninstalled/reinstalled Plex, but I get all the same messages that my server is unreachable and have no access to my files. Other suggestions?

There is no active VPN on the PC or NAS, correct?
You used http, not https, and the NAS IP address? Ex: http://10.1.2.3:32400/web
And there is no response at all, not even the 503 maintenance message?

Try http://syno_ip_address:32400/identity.
You should see some XML. Do you see claimed="1" (or 0)?
This would confirm that Plex is running and in a claimed (or unclaimed) state.

Try rebooting the NAS, then try accessing Plex once the NAS is fully booted. Sometimes a reboot will clear out some cobwebs. Use an incognito/private browser window to bypass any ad blockers, cookie cutters, etc that might get in the way.

If you still cannot get into Plex, then time to look at the log files.

  1. Stop Plex
  2. In File Station, navigate to the Plex Data Folder, /PlexMediaServer/AppData/Plex Media Server
  3. Right click on the Logs directory and choose Compress to Logs.zip.
  4. Upload Logs.zip to the thread.

I know just enough about this stuff to get myself into trouble, Ford. I’m not running VPN on computer or NAS, but when I type the address as you’ve listed, I get:

This site can’t be reached

syno_ip_address took too long to respond.

Try:

ERR_CONNECTION_TIMED_OUT

Here’s the log:

Logs.zip (1.0 MB)

Use the IP address of the NAS, 192.168.87.37.

The logs show no problems.

Start Plex Media Server.
Wait 2 minutes for it to fully start.
Go to http://192.168.87.37:32400/web

EDIT: The only other thing I can think of is that the Synology firewall might be blocking things. You could try disabling it test if it makes a difference. Synology Control Panel → Security → Firewall. Uncheck “Enable firewall,” then Apply.

Thanks, Ford, I had used the correct IP address previously. I’ll toggle the firewall off and try that as soon as I can and see if that works.

Just wanted to update you that I toggled off the firewall, and it fixed it. I really appreciate your help with this, Ford, thank you!
