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 everyone,

Sorry for the delay, we're still investigating the issues but we've not been finding any leads based on internal testing.

We're looking to do some more live traces with a broader scope that the previous tests. If you're interested in participating, can you please let me know your availability between 0900-1700 during the next couple of weeks? (You can PM me from my profile page: @JonathanB).

Based on previous sessions we'd be looking at around about an hour on call with one of our support staff, and they'll capture addresses and timestamps for the errors with you, whilst they feed back to our senior Tech teams on the other line.

Just to check, I've only seen new posts from @Nameless, are we still seeing these intermittent SSL errors as frequently recently?

Thanks,
Jonathan

It still happens to me. I've recently changed to Firefox to confirm the issue as Chrome definitely hides the issue from the user. Unfortunately I am unable to assist due to work commitments during that time-frame.

Do any of your team use the product, perhaps if they did it would at least help replicate the issue.

Hello and thank you for your update

I can help with tests and would recommend sending a similar message to the MVNOs that also share Three's underlying network as this issue affects them as well

Additionally it may be ideal to send a message to all Three members so that they can also contribute if they are experiencing these issues - This thread may have many posts however it is not displayed in a prominent fashion when viewing the forums...

Yes. No change here.

Happy to help out, if it is likely to lead to a resolution. I'm going to be honest with you though, I struggle to see how it is going to turn up anything that hasn't been discovered already.

Thanks for the update @JonathanB . No change from my experience - I think most of us have just given up reporting the status quo of errors and have been getting used to recurrently using VPNs to deal with it.  I'll drop you a DM with a potential slot or two I can do.

[EDIflyer]

Hopefully you got my DM @JonathanB - I messaged you yesterday but haven't heard back yet - one of the potential slots was tomorrow but guessing that might be too soon!

Hi @EDIflyer,

Yes message received thanks. I'm just waiting on feedback on which is most suitable to pull together the supporting teams, will let you know ASAP!

Thanks,
Jonathan

Or in my case, left for another ISP 🙂 However, I'm still following closely, as family are still affected, and remains to be seen what happens when my next contract is up to if ever resolved

Another check-in with no changes

The incidence of the error is still highly variable but it is still there

Have there been any changes for yourselves?
