I am using a 12.6 SP1 Policy Server and Web Agent 12.52 SP1 CR00 (GA).
I am receiving the below error while registering the Web Agent with the Policy Server:
" Registration failed: Unable to connect to policy server"
There are no network issues between the Policy Server and the Web Agent.
SiteMinder Policy Server Version: 12.6.01 Policy Server OS & Bit version: Windows 2012R2 Web Server Version: IIS 8.5 Web Server OS & Bit version: Windows 2012R2 ( 64-bit) SiteMinder Web Agent Version: 12.52 SP1 CR00 (GA)
IIS 8.5 is only supported with Web Agent 12.52 SP1 CR2 and above:
Download and install Web Agent 12.52 SP1 CR2 and above to solve this issue.
