Reverse proxy by Nginx

[SanmerDev]

I run an Nginx service by docker (host all my sites on one server), but weblate (run in docker) always displays 502 Bad Gateway.

• docker-compose.override.yml

  weblate:
    ports:
      - 8080:8080

You seem to be running nginx in Docker, so it cannot access localhost port 8080.

After I adjusted the network settings, it worked normally. Thank you.
