Is anyone else occasionally getting a 'connection down' error from Chrome (or 'Secure Connection Failed' from Firefox) when changing page - if I hit refresh it works fine. At first I wondered if it was the site I was using but have noticed it on multiple different major websites over the past couple of months and not noticed it from other locations where I don't use Three Broadband so does seem to be related to the router/connection (this is via wired Ethernet too, so not a WiFi problem). I've tried changing DNS server in case that helps but no difference.
It mainly seems to happen when trying to first load a site or (annoyingly) at checkout when a different site is being loaded as part of the checkout process. It certainly doesn't happen everytime but does happen with reasonable frequency. I've also noticed I often get it when trying to pull/push from/to Github too and have to do so a number of times for it to work (browsing the Github website works fine).

If its any use, I have a small web (streamlit) app making use of an old Raspberry PI. This would allow your network engineers attempt to trigger the SSL errors when they wanted, without needing anyone else 'on the line'.. PM/reply if you think this would be useful and I can provide access information.
On a button press it runs though a list of pre-defined URLs and reports if any errors occur.
This is running from my own Three connection. Currently, I don't think I'm getting as many errors as other users though.
