If the server is not listed in Authorized Devices, then it is unclaimed.
The last log file you uploaded shows errors communicating with hosts at plex.tv. If the server cannot communicate with plex.tv, then it cannot be claimed.
I did not see any log entries that mention database corruption, the problem in the post you referenced.
Suggest you try the following.
-
Configure Plex to not run on startup.
If Plex Media Server is running, right click on its icon in the menu bar and uncheck run at startup.
-
Authorized Devices
- Verification. If the server is listed, delete it
- https://app.plex.tv/desktop/#!/settings/devices/pms
- Verify
Plex ServerWindows Network Settings
Win 10 (11 will be similar): Settings → Network & Internet → Properties
- Network Profile must be Private, not Public.
- Verify the IP Address and Subnet Prefix are correct.
- Verify the Default Gateway are correct (usually the IP address of your router)
- Configure the server to use public DNS servers - 1.1.1.1 (Cloudflare), 8.8.8.8 (Google), or 9.9.9.9 (Quad9)
-
Reboot the Plex Server
-
Verify connectivity to plex.tv
- Open a Command Prompt window (Win+R, enter CMD)
- nslookup v4.plex.tv
- curl http://v4.plex.tv
- You should see the same as below. The IP address for v4.plex.tv may be different based on your location.
c:\>nslookup v4.plex.tv
Server: one.one.one.one
Address: 1.1.1.1
