I happen to have a test project that is created in angular 17 and communicates with a python backend.
The thing is that I would like the communication to happen internally through the python service but when I use as host :

this.http.get('http://service-a:5000/message', { responseType: 'text' })
      .subscribe(data => this.messageA = data);`

To connect to the back I get an error in the browser ERR_NAME_NOT_RESOLVED, I have tried to access the pod with angular and do a wget with the same url

wget -qO- http://service-a:5000/message
Hello from Service A!

It returns correctly the response from the api but when I try to do it from the browser it only throws errors
Does anyone know how I can communicate internally using the service? I leave the deployment.yaml for you to see it.
