Skype for Business 2019 and Hybrid configuration failing

MK GURU 1 Reputation point

We had SFB 2015 Hybrid configuration setup and working nicely. When we upgraded to SFB 2019 recently, the hybrid wizard (on SFB 2019 MACP)is not completing. It fails with error message (see screenshots)

MACP error

Fiddler output on error


Microsoft Powershell module [2.3.1] has been installed.

Followed most of the instructions from here.

Any help/advice would be much appreciated.
