VCenter Windows Authentication

[Bankesy]

Good afternoon all,

 

I am having an issue logging into VCenter with Windows Authentication, everything was fine until a few days ago but now I receive this error:

"[400] An error occurred while processing the authentication response from the vCenter Single Sign-On server. Details: Status: urn:oasis:names:tc:SAML:2.0:status:Responder, sub status: null."

 

We have been steadily migrating VMs off VCenter to Azure HCI but I can't imagine what changed since Friday to cause this error, I even put the last migrated VM back just in case there was something I had missed.

 

Does anybody have any advice or guidance on this please?

 

Thanks
