Every time we are logged in to CUCM pub and step away when we try to log back in we get the below error

HTTP Status 400 - Invalid direct reference to form login page

Using Firefox 66.0.1 64-bit on Windows 10

Known bug?

Close out all your browser tabs, then try again.  Happens on other versions, too.

-r

Yes closing the browser and restarting does work.  However this can be frustrating for some people.  Is there a fix for this?  Is it a known bug?
