As always in IT you have to deal with weird things daily.
We deployed VMware to a customer several months ago, and while in the need to perform some administration tasks we found out the vcenter6 web console wasn’t loading anymore. To be precise, after login we were redirected to a blank page. The same behavior was replicable on Internet Explorer, Microsoft Edge, Google Chrome and Mozilla Firefox. en plein!
Luckily the console was working on a box: a Windows 10 with Google Chrome 59.
