iDRAC 7 Virtual Console Plug-in Type HTML5 = Failed to connect viewer due to Websocket exception.

Upgrade DRAC7 to firmware 2.30.30.30 just to get HTML5 access to console

HTTPS gave certificate error (expected) , so today I uploaded my wildcard certificate:

It worked fine, so no error, now I have proper certificate.

But on HTML5 access in Firefox/Chrome 62 I get only error:

Failed to connect viewer due to Websocket exception.

IE does NOT work at all

Any idea what that means? AND how to fix it?
