Any help or hint would be greatly appreciated it.
I have two angular apps.
One running on port 30003 called issuer web services on port 30001.
One running on port 30004 called verifier web services on port 30002.

I have two spring boot web services.
One called "issuer web services" is running on port "30001".
One called "verifier web services" is running on port "3002".

I am running both apps using "minikube".
The Angular app seemed to have problem connecting to the web services.
The Angular app "issuer" cannot connect to web services 30001.
The Angular app "verifier" cannot connect to web services 30002.

Here is my work:

Here is the error I get in the console:
