WINRM issue

I receive an WINRM issue when running the deployment (it has worked with the same code 2 month ago).

New-AzResourceGroupDeployment : 23:29:03 - The deployment 'azuredeploy' failed with error(s). Showing 1 out of 1
error(s).
Status Message: At least one resource deployment operation failed. Please list deployment operations for details.
Please see https://aka.ms/DeployOperations for usage details. (Code: DeploymentFailed)

Configuration 'CreateADRootDC1' completed with error(s). Following are the first few: WinRM cannot process the
request. The following error with errorcode 0x80090350 occurred while using Negotiate authentication: An unknown
security error occurred. \r\n Possible causes are:\r\n -The user name or password specified are invalid.\r\n
-Kerberos is used when no authentication method and no user name are specified.\r\n -Kerberos accepts domain user
names, but not local user names.\r\n -The Service Principal Name (SPN) for the remote computer name and port does not
exist.\r\n -The client and remote computers are in different domains and there is no trust between the two
domains.\r\n After checking for the above issues, try the following:\r\n -Check the Event Viewer for events related
to authentication.\r\n -Change the authentication method; add the destination computer to the WinRM TrustedHosts
configuration setting or use HTTPS transport.\r\n Note that computers in the TrustedHosts list might not be
authenticated.\r\n -For more information about WinRM configuration, run the following command: winrm help
config.\"\r\n\r\nMore information on troubleshooting is available at https://aka.ms/VMExtensionDSCWindowsTroubleshoot "

Start with the reported New-AzResourceGroupDeployment output and the VM extension errors for CreateADForest1 and CreateADRootDC1.
