Hey all! I’m having an issue that’s probably simple but I can’t seem to work it out.

For some history (just in case it matters): I have a simple server running docker and all services being defined in docker-compose files. Probably doesn’t matter, but I’ve switched between a few management UIs (Portainer, Dokemon, currently Dockge). Initially, I set everything up in Portainer (including the main network) and migrated everything over to Dockge. I was using Traefik labels but was getting a bit annoying since I tend to tinker on a tablet. I wanted something a bit more UI-focused so I switched to NPM.

Now I’m going through all of my compose files and cleaning up a bunch of things like Traefik labels, homepage labels, etc… but I’m also trying to clean up my Docker network situation.

My containers are all on the same network, and I want to slice things up a little better, e.g. I have the Cloudflared container and want to be selective about what containers it has access to network-wise.

So, the meat of my issue is that my original network (call it old_main) seems to be the only one that can access the internet outbound. I added a new network called cloudflared and put just my Cloudflared container and another service on it and I get the 1033 ARGO Tunnel error when accessing the service and Cloudflare says the tunnel is down. Same thing for other containers I try to move from old_main, SearXNG can’t connect, Audiobookshelf can’t search for author info, etc… I can connect to these services but they can’t reach anything on the web.

I have my docker daemon.json set to use my Pi-hole for DNS and I only see my services like audiobookshelf.old_main coming through. I also see the IP address of the old_main gateway coming into Pi-hole as docker-host. My goal is to add all of my services to new, more-specific networks then remove old_main but I don’t want to drop the only network that seems to be able to communicate with the web until I have another that can.

I’m not sure what else to look for, any suggestions? Let me know if you need more info.
