SSL Server Test fails when IPS do decrypt

Question asked by David Larsen on Nov 30, 2018

We have a Cisco Firepower running IPS.

When doing SSL Servertest without Decryption, the test works.

When doing SSL Servertest while Firepower decrypts, the test fails with ": Assessment failed: Failed to obtain certificate"

 

There is a note on the error telling uou to check if there is an IPS device inserted, and there is.

Does it mean that SSL Server Test does not work through IPS, or have anyone experience on how to make it work?
