I have the exact same issue after updating to 6.7.0.51000. This isn't related to the browser. Chrome or Safari behave identically.

Failed to load resource: the server responded with a status of 401 ()

message = ResponseError OK, status: 401, message: Http failure response for https://vmcenter.example.com/ui/certificate-ui/ctrl/vecs/login: 401 OK, url: https://vmcenter.example.com/ui/certificate-ui/ctrl/vecs/login
stack = undefined

Any ideas how to solve this?

Hi,

Same issue with Edge.

I solved it by first attempting to open the vCenter interface with the Flash mode (no longer possible on my laptop because Flash is now prohibited), then by opening tthe interface with the HTML5 mode.

Unfortunately, the error reoccured later, probably after a logout/logon.

If it can help.
