Error 400 logging onto vCenter web client

This post was originally published on this site

Hi all,

 

Just started having an issue when trying to access vCenter from the web client. Initially whilst trying to access I received a “root certificate cannot be null” error. I rebooted the appliance. Now when I try and login I am receiving an error that states: “400 An error occured while sending an authentication request to the vCenter Single Sign On server – An error occurred when processing the metadata during vCenter Single Sign-On setup – null” We are running version 6.5.

 

I did some reading and a few folk found that a time difference between the ESXi host and the appliance caused the issue. I logged onto the host / server appliance, and the time was incorrect on both. I have since changed this so that they both have the same time, however I still get the same error.

 

Any ideas?

 

Thankyou,

Paul
