Exchange 2013 PowerShell "500 Internal error"

Hello Experts!,
I have installed a new CAS server into existing environment.
Exchange powershell was working fine and was connecting to local exchange server, after changing the VirtualdirectoryURLs and iisreset, its give me strange error. Not seen this before.
Along with the above changes, SSL certificate was also changed with wildcard cert *.domain.com
The Powershell virtualdirectory URL has not been changed, its default ex13-cas.domain.com

VERBOSE: Connecting to ex13-cas.domain.com.
New-PSSession : [ex13-cas.domain.com] Connecting to remote server
ex13-cas.domain.com failed with the following error message : <!DOCTYPE html PUBLIC

OK, Not sure what was the reason, but before making any changes to "bindings" the Powershell started working as expected.
By the way, is there any other dependencies for adding a Exchange 2013 CU23 into the environment of 2013 CU6?

Please go ahead and install CU23. There is no major changes in dependency only Exchange level changes.

Yeah, I did search around, did not find much except that it will extend the AD schema, but that's fine.
Its installed. Now time to troubleshoot some crazy environment autodiscover.

I will mark this as solved.
