Issue/Introduction

Getting an error when trying to add a new Internet Site Server to the CEM Gateway.

 "Failed to validate Server Certificate"

Some of the possible causes:

• Gateway is not able to communicate with Site Server
  • TLS mismatch. 

Resolution

Make sure TLS settings are the same on SS and GW, as enabling TLS 1.2 everywhere resolved this issue.
