My first post on this top seems to have been marked as spam, so I'll try again.
Recently I started having issues accessing certain websites, but others were just fine. I eventually narrowed it down, with some help to whether I was accessing them over HTTP or HTTPS. I access the majority of websites using HTTPS and that works fine, but if I have an old bookmark that uses HTTP it fails, e.g. trying to load google.com via HTTP fails but over https it works just fine. when it fails it waits for a while then I get the error message "The connection to the server was reset while the page was loading."
If I use a mobile hotspot instead of my home broadband the issue goes away.
Similarly a manual check for updates in Windows Update says "We couldn't connect to the update service. ", but it works fine if I use a mobile hotspot.
If I use a Linux box and "wget -d" I can see an HTTP get request, but it doesn't see a response.
My best guess is that something in the Vodafone network is blocking the response. It seems unlikely that Vodafone would block port 80, but I can't see what else it could be.
Has anyone else seen similar issues?
