Deploy rocket chat with docker

Question

It seems that rocket is connected to mongo, but it keeps loading when opening the website, so there is something wrong with my configuration.

I use the officially recommended docker configuration

The website is at this location

https://docs.rocket.chat/deploy/deploy-rocket.chat/deploy-with-docker-and-docker-compose First of all, I was confused when I first saw it. His description seemed to be that I only need to modify MONGO_URL and ROOT_URL. The problem lies in this MONGO_URL. I thought that user and pass were filled in casually, and then the env help would be automatically passed. I went to generate it in mongo, but I soon discovered that the rocket could not be connected. I found the reason for this was the host, because I asked Bing chat, and then after connecting, it prompted that the authentication information failed, and then I tried again. After searching many ways, I entered the mongo container and finally created a user and password. The final status was that it didn't seem to report an error, and then it kept loading when I opened the website.
