Recently, I took over management of some servers, and I can no longer connect to our vCenter to manage our VMs. We don't have SSO and as far as I know, we only have one account "admin".
When I go on the web using server name, I get error as below:
A server error occurred. [400] An error occurred 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.
Check the vSphere Web Client server logs for details"
When use IP of the sever, I get following error:
[400] An error occurred while sending a logout request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - null. Back to login screen
I see a 90 policy enforced, however nothing I do seems to resolve the issue.
Solutions i have tried so far and did not help: restarting the server, reset password, I have check the logs and nothing to be found of recent. last logs were from 2019. the problem started monday 8/0602020 etc.
