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.

You don’t happen to have that link to hand? I’ve looked through the thread (I’m on mobile) but haven’t been able to find a link from him.

I already opened a case with the social media team (or at least added my details to the existing case) but other than a follow up "has it gone away yet" message from the social team, nothing has happened there. I initially got this message from @JonathanB explaining how to sign up / add my details, but he may have to prep the team 1st? Not sure. May be worth a shot anyway:

Please contact the Social Media Team by webchat. I've made them aware of the issue, and they'll help get this escalated with our Technical and IT service desks.

Yep, that's the one - thanks @hughesceri

I have this error dozens of times a day on all different devices. I removed adult lock as found it as possible solution online somewhere. I also tried to change default DNS - still nothing. Drops the connection anyway.

I spoke at work with one of my colleagues (he's software dev.) and said that's the reason he does not use 5G three (when working from home) as that was exactly the reason he left this network - constant problems with GitHub. And he live in completely different location to me.

I think also for me it's time to leave and go to fibre even when more expensive - at least it's stable!

I too have been having the same issues as everyone here. It was running pretty much flawlessly until firmware b14 reared its head.

Started noticing it with my ps5 and it was telling me I wasn’t connected to psn even though I was able to connect to everything else and eventually would throw me out of games advising it couldn’t confirm the license.

Then started getting random errors on banking apps stating request hasn’t gone through and to try again. Then the random ssl errors would occur throughout the day. The final straw was the router itself would disconnect for hours on end until I had to reset back to factory settings and this happened 3 days in a row which is unacceptable anyway but more so as my wife relies on the connection for work so I have had to switch over to my old huawei b525 4g router which is more stable but not what I paid for.

Are you any further forward to what a fix may look like? Or can you give the option to rollback firmwares to see if that resolves our issues? I am on a rolling 30 day contract and will be leaving for ee which we’ve had before (slower speed) but rock solid connection wise if the issues are not resolved quickly. It’s not enough to say we’re looking in to it for weeks on end I’m afraid.

Been away for a week and hoped this would be resolved by now but appears not. I am struggling to understand how progress hasn't been made in all this time. Can we have a proper update on this issue and when a fix will be provided as it simply isn't good enough carrying on like this

FWIW I swaped my phone card with the router card and set the APN back to 3internet. Still getting errors when running @EDIflyer's test

for i in {1..100}; do curl -I --no-progress-meter -o /dev/null https://github.com || true; done;

I don't know if things are getting worse for me or whether I'm relying more on github.com and ghcr.io urls than previously, but my Three home broadband is starting to become unusable for anything related to software development now.

Even the simple act of updating or installing a package using homebrew on the mac is very difficult, as each of the (many) dependencies for a package requires a couple of hits to ghcr.io and when one of those fails I have to rerun and rerun until it works - or like I've had to do today, go to a place with public wifi and run it there.

How long can we expect this to continue? If there's no sign of a workaround, how long until Three starts to really acknowledge the issue and give us something that can help, e.g. some sort of paid VPN service.

Apologies if this is not the relevant forum to start a conversation about compensation etc - I'll happily try something else that doesn't require any form of subscription / payment, but I'm not going to use a limited, free VPN as that's just a short term workaround that will eventually hit a data transfer limit.

This really is quite disappointing I have to say and generic technical guidance really isn't the answer for customers.

I got fed up with the problems as I need a reliable and fast connection, therefore decided to try an expensive fix. I bought myself a Zyxel FWA710 5G outdoor router and mounted it in my loft next to the Three supplied NR5103E, then swapped my SIM over.

For the last week running with the FWA710 using the latest OEM firmware and IP Passthrough mode I haven't experienced any issues other than a loss of service overnight at the weekend that I suspect was mast maintenance as it started at exactly 2am and lasted an hour.
