Plex server offline both Windows and QNAP

Server Version#: Latest
Player Version#: Latest
For the past 4 days, my Plex servers (Windows and QNAP) show offline. Nothing was changed at my end and I have restarted the servers with no luck!

I tried to connect using Windows APP and Android APP and none is working!

Please I need your assistance.

Thank you!

Please provide the server logs

I have attached the logs. Thanks!

Looks like you have a double NAT setup, and that will not work

See: https://support.plex.tv/articles/200931138-troubleshooting-remote-access/ and look for Double-NAT
