Ok, so that sounds like either a DNS issue or a reverse proxy issue. Did you configure your domain/subdomains to point to the public IP address of where you’re setting things up? Are you using the reverse proxy in the guide or do you already have a reverse proxy and you’re adding ESS domains to it? Did you configure port forwarding on your router?

I have had issues with accessing my locally hosted services via domain name while on the same network. My router doesn’t like to route internal traffic back to its own WAN port. Can you access it from something on a different network (cellular data)?

It’s not quite as simple as a single docker compose, but the Element Server Suite for hosting a matrix home server (synapse) was fairly simple to get working.
