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,

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?

No change here. Experienced the issue just today on scummvm.org

I will add this website to my list of testing sites - 99 websites in my list and counting

As far as my testing has shown thus far, there is no website that is immune from the problem however some of those mentioned in this thread do seem to generate the problem more often when using certain bands...

No changes here - still recurrent issues if not on a VPN.

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.
