Issues with deploying to an ADFS server

Latest version of CTW (Certify/5.1.3.0 (Windows; Microsoft Windows NT 10.0.17763.0))

When we attempt to deploy to the ADFS sever we see this in the log:

2020-09-03 08:07:43.782 +10:00 [INF] Task [Deploy Certificate to ADFS] :: Task is enabled and primary request was successful.

Any ideas?
