Hello, strange SAP6 problem -- a service user is getting ICM_HTTP_CONNECTION_FAILED from our Test environment when they try to call a REST service using HTTP_CLIENT. All other users can run the call without issue; i.e. there is no setup issue with the call, it is specific to the user. And the same user is able to make the call in our Dev environment without a problem.
Security claims the service user has the same access in Test and Dev, but I don't see how else we could have this problem. I'm contemplating asking them to create a new user from scratch, what does ABAP Forum think? Maybe I'm missing something here.
