Intermittent connection issues loading/changing site- secure connection failed/site can't be reached

[EDIflyer]

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).

I'm using a NR5103E with Firmware Version V1.00(ACBJ.0)b14 - I tried rebooting it but to no effect.

Yeah, Docker can become pretty much unusable without having to shell out for a VPN. Much like git

Found a website that fails 50% of the time for me when using the test script, but no problems when turning on a VPN

https://hotukdeals.digidip.net

Results after running the command 10 times:
Successes: 56
Failures: 44

Hope that helps someone more technical than me work out what is going on

Still no updates, the issue also discussed here with traces and proof of issues

@PeteG we were told this is being looked into but still months go by and no updates?

Did a quick test yesterday on the unusual band combination of B3 with N78 appearing twice

Testing speeds were averaging closer to 800Mbps rather than 600Mbps despite the time of day

More importantly, there have been no changes

Cloudflare's WARP continues to work for myself despite the download speed reductions due to its overhead

I wonder if such mitigations will still be needed under Vodafone's systems although iD Mobile seems to be absent in the announcements unlike the other MVNOs

I left Three during my cooling off period and jumped to talkmobile, a Vodafone NVMO (I think it might even be owned by Vodafone).  It certainly does not have the TLS problems that Three has.  I do get connections dropped from time to time when streaming internet radio, but I had a bit of that on my old landline too, although talkmobile is definitely worse at it. I don't notice issues with anything else.

I think it's a good service.  Cheaper than Three and a one month rolling contract so easy to leave if it becomes rubbish. The only downside is there's no router - it's a mobile phone contract that allows tethering. I'm technically minded, so rolled my own router on a Raspberry Pi and plugged an old mobile phone into a USB slot.  Not as fast as Three, but faster than my landline ever was so I'm happy.

Been trying to do some remote working today from home. Had so many issues trying to connect to the vpn/microsoft authentication/remote app. This is actually horrible

[torz77]

Yep. It is thoroughly broken for a lot of use cases. Basically terminates the connection early. Welcome to the black hole that is this thread. Don't expect a resolution, as there has not been one for nearly 2 years now, but at least you aren't suffering alone.

Not that this is much consolation.
