hi @cnlxh, Have you mentioned the port in docker-compose file to expose the app to external network (i.e. Host and container port mapping).
If you can show your docker-compose file , it can help to understand the problem.
This kind of problem also occurs when inbound traffic is not allowed on the host port number you mentioned in docker compose file…

hi @cnlxh, yes you need to run a haproxy container above your containers to balance the load between them and to made your application highly available.
