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.

Still the same here.  Just had a problem accessing jackpotjoy.  That site is buried under god knows how much javascript that hides the issue we have on here with SSL failure, it just manifests itself in a stalled loading page which sorts itself out if you just reload the page (I'm 99% sure the stalling issue is caused by Three's packet inspection).

Hey it's not all doom and gloom though... it's this thread's birthday in 3 days!!! :yay:

Another check-in with no changes to the usual issue

There were some issues earlier this week with broadband connectivity that was quickly fixed by disabling the B3 band with no significant changes to download or upload speeds however this has been reverted

I've been suffering with this for ages. I'm using a Three Unlimited SIM in a my own router that's had no firmware updates in years. It was never this bad when I originally started using Three.

I also use Cloudflare's sDNS service but it doesn't help.

Welcome to the black hole. A 45 page thread where no one will admit that there is a problem, much less find a solution.

Only 8 days to go before we celebrate our first birthday.

I think they're actively trying to get rid of people.  Had an issue past 2 weeks of about 15mbps, now I'm getting 2-5mbps, whilst connection is still 5G on the router and 250m from the mast. Not isolated to me as neighbours and their phones have the issues too, so its 100% the mast and/or area.  Eventually they rang back and said theres a problem and just "do you want to cancel right now" (I'll have to make some arrangements for something else but I'm off work ill too).  Of course still the SSL issue too.  Despite them acknowledging they have network issues too, the network status pages still say there are no reported issues for our postcodes, full on lies, if not fraudulent as people could sign up based on these reports

That's disappointing to hear

It's really reproducible when trying to log in to the nsandi.com website

I was on nsandi yesterday and got hit at the login page. Thankfully only one reload to get it working but still that's not what you want on a financial website is it?

Any updates @JonathanB ?

I just had the SSL error again browsing Morrisons. 😞
