Need help configuring Caddy with Nextcloud and Notify Push

@Steasenburger

from the following remote: <my-public-ip>

indicates your systems talk to each other over the internet. This is expected in case both are using public FQDN. in this case your caddy must trust your as a trusted proxy.

You could also shortcut the communication inside of your Docker system following the approach I described in Probably DNS help with NC Docker + Collabora + Wireguard tunnel. adding

    networks:
      proxy:
        aliases:
          - cloud.mydomain.tld

will make all docker containers in network proxy to access cloud.mydomain.tld without the internet loop.

Maybe How to verify notify_push works correctly? helps with troubleshooting
