Docker containers: MongooseServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017

Hello,

So I currently stuck on this issue for the past couple of hours. I have a linux server with my MongoDB database running inside of a docker container - 0.0.0.0:27017->27017/tcp. I am able to connect it from the outside of the vps itself. But the issue is that I am running another docker container trying to connect to the MongoDB server on the same vps and it results in this error.

For the mongo uri string I tried the following
mongodb://username:password@127.0.0.1:27017
mongodb://username:password@0.0.0.0:27017
mongodb://username:password@localhost:27017
mongodb://username:password@ipaddress:27017

For the ufw rules itself, I added the vps’s IP addresses, 127.0.0.1 to allow connection to port 27017, but no matter what I keep running into the same issue.
