Remote Desktop Connection Error : Authentication error occurred. The function is not supported

I am trying to connect Remote Desktop to Azure VM. All the connection settings and credentials are correct. However I am getting below error from RDP.

Remote Desktop Error during Authentication error occurred. The function is not supported.

Remote Computer : xxx.cloudapp.net This could be due to CredSSP encryption oracle remediation.

I think a better aproach would be to update both your client and server since it's a security threat not to. https://support.microsoft.com/en-us/help/4295591/credssp-encryption-oracle-remediation-error-when-to-rdp-to-azure-vm

To resolve the issue, install CredSSP updates for both client and server so that RDP can be established in a secure manner.

I figure out the issue. It is related to group policy. MS has released a patch for this. Below solution worked for me.

Go to -> Computer Configuration -> Administrative Templates -> System -> Credentials Delegation -> Encryption Oracle Remediation Open - Encryption Oracle Remediation-> choose Enable -> change protection level ->Vulnerable ->Apply
