Matrix, Synapse server can't be reached

I set up a matrix server and everything seems to be happy, but I can't connect to the server. Calling it with: matrix.myDomain.de results in ERR_TIMED_OUT

Calling it with: matrix.myDomain.de:8008 results in ERR_CONNECTION_REFUSED.

I get an answer when I ping matrix.myDomain.de from command line.

My guess is, that I'm missing a config that exposes the service to the internet.

This is what I did:

Setup Domain, SSL(let's encrypt), DNS entry
Setup folder structure (content in data/ is created by docker compose)

└── docker-compose.yml
docker-compose run --rm synapse generate

There I got the error message:

Network server declared as external, but could not be found. Please create the network manually using docker network create server and try again.

docker network create server
docker-compose run --rm synapse generate
docker-compose up -d

State of the setup:

docker ps

networks:

docker network ls

My question:

Am I missing something, do I need to connect the docker bridge to the container? My understanding is, that already is happening with the networks point in the .yml file.

I'm currently lost and couldn't find any helpful guide.

A timeout usually indicates a firewall issue.

Additionally, there is nothing in the information you provided that anything is listening on the default ports 80 or 443.

That's correct, there is no web server running. I picked up that some people are running reverse proxies with nginx, but I thought that was optional. If I specify the port 8008 I get a ´ERR_TIMED_OUT´, if not a ´ERR_CONNECTION_REFUSED´

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
