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.

So, around the 30th of October I reported here that things seemed to be working for me fine using 5G at home suddenly and out and about locally using 5G, and as I later discovered when back in the office one week the cell tower near the office was now delivering working 5G, whereas before that was a fail.. And also, every 5G tower I was connected to was working fine, though during this time I haven't ventured very far, maybe only a 10 mile circle over this period, but all has been absolutely perfect, not one connection error..

And that has been the pleasurable case since then.. Up until Wednesday last week..

It's now back to exactly the same weird behaviour as before, with apps galore failing miserably all the time, Netflix won't login, MS Authenticator doesn't want to know over 5G, banking apps erroring, gmail failing to refresh etc..

I don't know what Three changed in the region for that 5-6 week period, but please change it back again!

I can post the two cell towers that I can 100% vouch have been working fine for this period, and I don't believe you can't determine what was changed on those two towers from a software/hardware perspective, around the window of everything functioning perfectly..

If you have not done so already, send @JonathanB a direct message about this and I hope that this gets forwarded to the relevant departments quickly

I have not been lucky enough to have seen any significant changes where I am

Hi everyone,

Thanks for your patience. As I mentioned on the last couple of updates, we'll be running some further live traces soon. We've got this planned in for next week, so I'll hope to have a more significant update later next week.

Thanks,
Jonathan

Thank you for your update this week and thank you for continuing to issue weekly updates for us all

Between my last message and this message I can still confirm the following:

• Disabling Band B3 causes the issue to become rarer for myself
• The issue still exists

I will continue to test things from my end

Last week was fun - I lost a hard drive to mechanical failures and have now just remade the bookmark folder with the 100 or so problem websites reported here (Yes I did go through all 509 messages before this one)

With that being said, I have not had an opportunity to do some extensive testing recently due to my almost complete lack of PC usage and will start later today

How have things been for all of you?

I've seen no significant change.

Hi everyone,

Just to update you all, I'm waiting on more info about our next set of live traces from some internal teams. I'll reach out to everyone who has expressed interest as soon as I have clarification on the timeframes and how this will be set up.

Thanks,
Jonathan

I was having loads of issues with various things that needed to connect to the internet. I went through the guidance to turn off IPv6 and am now only using IP4. Fixed quite a few things, but still have issues with some sites. Very annoying if you want to buy something at Screwfix.co.uk as that just never works unless you go through a VPN, in which case it works fine.

Hi @BrAinZ,

I'm not sure if this is the same issue on the screwfix website. That's https://screwfix.com right?

Have you removed adult filter from your My3 account? I've seen a few instances where similar SSL errors do get returned by the filter triggering, and screwfix is likely to trigger the filter due to some of the age restricted items they sell.

From my understanding, there's not been any websites reported that always return these errors, these have always been reported as intermittent, although they can vary in frequency considerably. Does every attempt to connect fail, or do you mean that the errors are preventing you from completing an order in their shop/checkout processes?

Thanks,
Jonathan

Just a quick check-in with no changes

There have been no significant changes - Wi-Fi or Ethernet, everything is the same

Have there been any changes for yourselves?
