I am trying to upgrade from 4.0.0 and I get this as well. The only way I get it to work is if my TLS cert has localhost as the subject or alternate subject - not sure that will pass the governance test. And yes, I have host name verification turned off and I change the "app.origin.host" values for publisher, devportal and admin to the subject in the cert instead of "localhost" (according to docs). I may have to abandon this product as I am not seeing much action on issues here.
