Runner Containers not communicating to each other in a client server program in multiproject CI/CD

Hi All,
I have made two different projects. One project is having a server program which is listening at a particular ip::port, Another project is having client program which connects to the same ip::port which server is using.
I have one runner each for client and server project, when job completes on the server side server is waiting for the incoming requests but client container is not able to connect to the server container when it’s job complete and says “connection refused error”?moreover when i try to list down the
port that is listening inside server side container i don’t see port number that server program is using to listen?

inside config.toml file of server runner i added ip::port for listening also but that did not help either.

Any help will be highly appreciated.

Thanks.
