Glad you sorted it out. I can see we have the same NAS model, but I still can't make it work. That
MONGO_URLis already inside, so I just update it, then I add
Always the same error. Can't connect to mongodb.
Can you paste in the related errors from the mongo logs? It sounds like you are skipping the link step in the Rocket.Chat container if it can't connect at all. From the instructions:
LINKS: your mongoDB container > alias: db
Also check the port is set to
3000:3000for the Rocket.Chat container. Maybe posting all the env vars from both containers can help us troubleshoot?
