I went through all the possible articles about this problem on StackOverflow and Github and none of the solutions works, that's why I decided to post another question.
I've setup mongo with mongo-express on docker-compose and when I run it everything seems good except that when I try it through web browser it says ERR_EMPTY_RESPONSE
Docker-compose:
version: '3.1'
services:
mongo:
image: mongo
restart: always
ports:
- 27017:27017
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: example
mongo-express:
image: mongo-express
restart: always
depends_on:
- "mongo"
ports:
- "8081:8081"
environment:
ME_CONFIG_MONGODB_ADMINUSERNAME: root
ME_CONFIG_MONGODB_ADMINPASSWORD: example
ME_CONFIG_MONGODB_SERVER: mongo
Logs from docker mongo-express:

basicAuth credentials are "admin:pass", it is recommended you change this in your config.js!
Docker ps:

I tried also as it was suggested on other posts to run mongo-express on 0.54.0 image version. Below is the result:

}
All looks good, except of I can't access mongo-express from outside docker container. Do you have any other ideas what might be wrong?
