XenMobile can't talk to PKI web enrollment server

Jeroen Tielen1709158489


While setting up CBA I'm running into this error which is driving me crazy. 


I have 1 PKI server which hold all roles. 

I can access the certsrv page (username and password) and can request certificates. 


When configuring this server as a Microsoft Certificate Services Entity in XenMobile I cant test the connection. 

Error: Connection Failed. 


In the debug log I see the following:

I know 100% sure that the credentials are correct. The PKI server is a server 2016 and XenMobile is


Anyone seen this strange behaviour before?
