  • SSL Binding Error (Request Not Supported)

    We had a working IIS server and now the HTTPS binding does not have a certificate associated to it.  Attempting to add the certificate results in an error stating the request is not supported.  


    IIS 7.5.7600.16385

    Edit HTTPS binding

    Associate certificate

    There was an error while performing this operation

    The request is not supported. (Exception HRESULT: 0x80070032)

    Any thoughts?  Group policies too look for?

    Any thoughts?  Group policies too look for?  

    This issue is may be caused by group policy setting that control whether outbound NTML traffic is enabled.By default, the GPO policy 'Restrict NTLM: Outgoing NTLM traffic to remote servers' is configured to enable outbound traffic. If this policy is changed to 'Deny ALL',certificate enrollment fail with this message.

    You could try to change the policy to allow outgoing NTML traffic.

    Download and run IIS Crypto. Make sure TLS protocols and encryption algorithms are enabled.

    Additionally, check if secure cipher suites are enabled. In the server I troubleshot, there was only one cipher suite active. This caused the both binding and Windows Update issues. We followed the steps below to use default cipher suite list in the server which solved the issue:

    1. Go to “Start > Run“. Enter: gpedit.msc
    2. In the left pane, expand “Computer Configuration > Administrative Templates > Network > SSL Configuration Settings
    3. In the right pane, right click “SSL Cipher Suite Order” and choose “Edit
    4. Save the text inside “SSL Chiper Suite” field to a Notepad for backup
    5. Select “Not Configured
    6. Click “OK
    7. Restart the server (gpupdate doesn’t enforce this setting. You should restart the server)
