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).

All seemed eerily fine for a while but https://groceries.morrisons.com/webshop/startWebshop.do eventually gave the same PR_END_OF_FILE_ERROR message
Since WARP works and they are cheaper than Three for myself, I guess I will save some money by switching
I have not checked the forums for iD Mobile but I wonder if it would be ideal to start a thread there to inform users about this problem and linking here?

With Three's broadband, I know that there can be an issue when using the APN 3internet (Broadband default) instead of three.co.uk (Mobile default) so if they are not using 3internet then that might be the reason
I did switch to three.co.uk because it had less issues overall and was ultimately more stable but the same end of file issue still happened which is how I ended up finding Cloudflare's WARP
I guess we could technically try out all of the APNs from these providers although I am not expecting miracles as the underlying network is the same
With that being said, if I do end up transferring to one of these related networks (Deals are tempting), I will still read this thread hoping for a solution

I use a iD mobile sim in my mobile..
A quick check shows that the problem still exists when using iD mobile..
Three (Three Sim, 3internet APN)
iD Mobile (iD mobile SIM, id APN)

I see the same issues with my iD Mobile sim in my phone

By any chance, have you used the APN three.co.uk and, if you have, which APN is the most stable for yourself?
So far, iD Mobile's APN has been roughly equal to three.co.uk in my usage although I am now using Cloudflare's WARP over the top to prevent any further issues

For me, I tend to find 3internet being a touch better.
Its a bit odd since it seems to affect which sites get the SSL error more often. On three.co.uk I seem to get more issues with VisualStudio, apple and microsoft sites, which affects me more with work.
But its just observational rather than any measured results, and the frequency of errors seems to change each time I reconnect anyway.
Also get Captcha'd a lot more when using three.co.uk since its nat'd

I recently got Three 5G BB installed and have experienced this "Secure Connection Failed" screen quite a few times randomly. I guess this issue has never been solved judging by how old this thread is. I have a ZTE MC888 hub.
Any updates on why this may be happening?
This thread does not show up in the most recent so there is a good chance many people are unaware that this is a significant issue.

Yes unfortunately its definitely still a huge issue and mostly seeing tumbleweed by way of updates. A lot will put the issue down to their phones or tablets etc playing up. For connection errors some browsers will auto retry and correct itself etc but it causes many issues more than just the browsers, like apps/games updating, multiplayer connection problems, files not completing. I dont get how Three engineers are relying on people in here doing the testing when it must be fairly easy to replicate themselves considering how it happens several times per hour in my browser etc across all devices

If you need a workaround for this issue, a VPN or Cloudflare's WARP will do the job
For myself, I am using Cloudflare's WARP and had used it on Three without issues but now I have gone with iD Mobile (Three wearing a trenchcoat) because it ended up being cheaper

It's been pretty quiet on here with official updates, last post from @JonathanB was over a month ago.
Would be nice to get some official update on the matter, even if it's "we haven't done anything yet".
Makes it look less like the subject is being ignored.
