HTTP requests between services not reaching destination container

If you're experiencing issues where HTTP requests from one service to another are not reaching the destination container, the most common cause is missing port specification in your request URL. When making HTTP requests between services, you need to include the port number in your URL. Instead of using just the service name like http://service-name , use the full format: http://service-name:PORT Where PORT can be: containerPort service port app listen port Most services are not listening on the default HTTP port 80, which is why specifying the correct port is essential for successful inter-service communication.
