Online exam connectivity issue: pearson vue / wowza.com

[#1]

A member of my household is preparing to take an exam with Pearson Vue ( https://home.pearsonvue.com/theiam/onvue ) online. They provide a system test to check that everything is ok. This fails with the following:

Video streaming connection results and requirements:

• Your home/office network failed to connect to the required video streaming service.
• The streaming connection requires that Wowza.com can be reached as well as a stable connection of at least 1mb upload and download speeds.

How to connect to our video streaming service:

• Contact your network administrators and ensure the following:
• Any network filtering software is disabled
• WebRTC WebSocket connections must be allowed to *.*.cloud.wowza.com on TCP port 80.

I can telnet to port 80 of cloud.wowza.com. The upload and download sppeds are fine in general. Not sure what else I can check.

Would be sensible to post your connection speeds.

They pass the requirements:-

Download: 56.04 MBps

Upload: 6.23 MBps

I don't have an answer, but you do have my sympathy.
Went through this twice with Pearson, one which left my daughter absolutely distraught due to their flaky systems.
