Error: Unsupported Video Type Or Invalid File Path

I couldn’t help but have a quiet chuckle at the sign up process for Microsoft Azure, which after signing in on IE 11 on Windows 10, you get the offer to “Take a tour of the management experience while you wait.”, which gives the following message on the video below:

Error: Unsupported video type or invalid file path

This was followed by Sign-in failed after clicking the button when told to proceed.

I managed to get my Azure login to work by clicking the button to use the Classic Portal.
