When trying to visit https://radical-prod-video-files.s3.us-east-005.backblazeb2.com/ on the Vodafone network, something within Vodafone is causing allot.com to be inserted into certain https connections such as the above. allot.com is issuing a fake certificate for the above website, which then fails the browsers' security checks and the connection to be rejected with the browser message net::ERR_CERT_AUTHORITY_INVALID
It appears that allot.com is hosted at Amazon Web Services and appears to be related to Vodafone Secure Net.
This is the same problem that WhiteKnight reported here: https://forum.vodafone.co.uk/t5/Mobile-Broadband/allot-com-trying-to-intercept-my-Internet-traffic/t...
Worryingly, allot.com continues to man-in-the-middle secure web connections even when Vodafone Secure Net is disabled.
I've spent around 30 minutes on Vodafone text chat and them a further 1h45 speaking to an Support Engineer on 191. So far, Vodafone don't seem to understand the issue or know how to resolve.
