The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent or invalid.

Cause

This error can occur if you're connecting via wsman to the wrong port. Note: If you don't specify a port, the connection will be attempted on port 80.

connect-wsman -connectionuri http://EXCH-2K16-2.exch2016.net/PowerShell -credential exch2016\sysadmin

Fix

To resolve the issue, specify the appropriate port.

To find out which port to use, run the following PowerShell command on your Exchange server:

Get-WSManInstance -ResourceURI winrm/config/listener -Enumerate

The default is 5985.

connect-wsman -connectionuri http://EXCH-2K16-2.exch2016.net:5985/PowerShell -credential exch2016\sysadmin
