I am experiencing an issue with a Railway service where the application is running correctly, but the public HTTP domain is unreachable.

Current behavior:

• The service deploys successfully.

• The container starts without errors.

• The Node.js/Express server is listening on 0.0.0.0:8080.

• MongoDB connects successfully.

• Logs confirm the server is running:

   Accounting Server running on port 8080
   Connected to MongoDB successfully
  

• However, accessing the public domain results in:

  ERR_CONNECTION_TIMED_OUT
  

Expected behavior:

• The service should be reachable via its public domain over HTTP.

Additional details:

• The application was working normally with the same deployment and configuration approximately one hour before the issue occurred.

• No code or configuration changes were made before the issue started.

• The public networking domain exists and is mapped to port 8080.

• The application correctly binds to 0.0.0.0 and the exposed port.

• The issue occurs even when accessing the domain directly in a browser (not only from the frontend app).
