WARN[0000] network nginx-proxy: network.external.name is deprecated ...

I run mailcown dockerized behind jlesage/nginx-proxy-manager.

In mailcow-dockerized docker-compose.yml I have

   nginx-mailcow:
      networks:
        mailcow-network:
          aliases:
            - nginx
        nginx-proxy:

and

networks:
  mailcow-network:
    [...]
  nginx-proxy:
    external:
      name: nginx-proxy-network

This has worked fine until today, when I updated mailcow dockerized with the update.sh script, which required updates to docker and docker-compose.

Now I get the error
WARN[0000] network nginx-proxy: network.external.name is deprecated in favor of network.name,

And when I go to the site, I get an error from NPM "502 Bad Gateway*

Docker version 20.10.21, build baeda1f
Docker Compose version v2.12.2

It seems like something changed in the latest docker-compose version, so the networks have to be defined in a different way? Please help.

The containers all appear to be running, and mail works as long as I don’t use the web interface.

I’m aware that this may be considered an NPM problem, but it is only a problem with mailcow, other containers works fine with the same setup.

Actually this was just a warning, resolved by changing

networks:
  mailcow-network:
    [...]
  nginx-proxy:
    external:
      name: nginx-proxy-network

networks:
  mailcow-network:
    [...]
nginx-proxy:
    external: true
    name: nginx-proxy-network

I still get the same error though, so I’ll close this and open another ticket being more specific.
