Nginx - 502 Bad Gateway

Hi Peter, thank you for reply.

I mean, after autmated display-registering by system. After them, CMS-Login becomes “502 …” without any changing by myself. Before the CMS was running smooth. Meanwhile i testing with a brandnew installation.
Hm…

The docker containers have standard ports
CMS (8888:80 and 8080:8080)
DB (32773:3306)
XMR (50001:50001 and 9505:9505)
phpMyAdmin (8081:80)

The Proxys:

  1. Signage over HTTPS (signage.synology.me) 443 to localhost 8888
  2. Local over HTTP (signagetv) 80 to localhost 8080
  3. Local over HTTPS (siganetv) 443 to localhost 8081

/1) for public access

Is that correct?
