Running VIP Authentication Hub, before giving the credentials to access the adminconsole, the browser stays on a blank page.
Using incognito mode with the browser, the issue can't be triggered.

It is not that VIP Authentication Hub uses the browser cache explicitly, it is something the browser does implicitly.
Caching by browser is not in control of VIP Authentication Hub, so, in case of this, try to select the checkbox in dev-tools "Disable cache" and then it worked fine.
After that, even with the Disable cache unchecked it works fine. So, there was something stale that the browser was serving from its cache that caused the issue.
It has never happened previously.
Select the checkbox in dev-tools "Disable cache" in dev tools to solve the issue.
