I fresh installed with docker compose up -d and then it run.
RocketChat container gives me this error every 30 seconds and crashes. There are no other logs on that container.

In the MongoDB log I get this message that Connection from IP 172.18.0.3 (rocketChat) was accepted. I tried to reinstall the whole docker compose ecosystem even deleting and pulling the images again but it doesn't work.

Research direction
Start with docker compose up -d and compare the Rocket.Chat and MongoDB container logs, focusing on the mongodb:27017 endpoint and the rs0 replica-set state shown in the error. Confirm that MongoDB has a primary and that the containers can communicate; done means Rocket.Chat stays running without repeated server-selection timeouts.
