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.

Hi,
Zyxel NR5103E

It is tricky as it can be bit random. It often happened when I went to https://www.hotukdeals.com/  then clicked on a deal for amazon. The browser goes to some affiliate link first which would give the connection was reset error then continue.

My old mast is fixed so getting fast downloads again, but 6 hours in and got my first connection reset error. When browsing www.hotukdeals.com then clicking on a deal for epic games store. Also the other normal symptoms, netflix takes ages to load, some apps fail to open and then work the 2nd time.

Hi @x-c311,

Thanks so much for this feedback. I'll pass this on to the team who are investigating in case it helps solve this. I'll let you know if there's any more info we need to check this out.

Thanks,
Jonathan

Hi @x-c311,

I've sent you a PM to request a little more info so we can add this to the investigation.

Did I miss a check-in this week?

There was a moment earlier this week when the B3 band kept dropping out and the B1 band was not chosen despite having a better signal most of the time so I had to disable the B3 band to force the router onto the B1 band

Apart from that, I am still recovering from the hard drive loss and accumulated backlog due to that and have not done as much testing however there have been no noticeable changes...

How have things been for all of you?

No change. Still abysmal

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
