A call to SSPI failed: The target principal name is incorrect

I have ported a simple method consuming MS Dynamics AX WCF Service from .net framework to .net core 2.0 (console application).

In .net core project I added the connected service with no problem. All types were auto-generated correctly and I didn't have to do much refactoring.
However when I call the client this is the exception I'm getting:
Could you assist me please?
I'm using VS 2017 v15.6.6
