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.

Thanks, glad to hear it is still being worked on - I was a bit surprised to receive an email from the Social Media team a few days ago asking if everything was sorted and working again when it was so clear on here that it hadn't been! 

It would be great to understand a bit about where the issue has reached and a potential ETA re any fix.

Hey @EDIflyer,

Sorry I haven't seen every email involved personally, but I've asked to be copied in going forwards. My understanding is that we're still trying to pin down the precise cause of the issue, but I'll see if I can find out any more.

Thanks,
Jonathan

So it's there any update on this? Been many weeks since this was raised and it is becoming very tiresome and irritating on a continual basis.

Awaiting further updates on this and when it will be fixed.
PR_END_OF_FILE_ERROR has been very prevalent this past week, multiple times every day.

I have had the same issues related here. It started happening a few months ago, it was fine for a year or so and I contacted support. They've swapped me from a Huawei hub to a Zytel hub, got a replacement SIM and it's all still happening. Connection is good with fast speeds but often get the connection failed error when loading websites or checking out. Reloading the page will fix it. It happens on all devices, when people come to visit it happens on their devices too. Happens on my ethernet cable connected devices too.

If I use a VPN this issue goes away. Sometimes I also get 400 bad request when running updates, this too goes away when I run a VPN.

I've been a Three 5G Home Broadband subscriber for just about a week now. I found this thread while researching the same intermittent connection issues listed by others. I have the same router model and firmware and only use ethernet to connect to a well tested Asus router (double NAT) and mesh setup that was previously connected to a BT Hub. Never had a problem from the BT hub.

I could also test using IP Passthrough if this is helpful?

Hi @BrummyGit,

Thanks I've sent you the same PM as the other community members that have posted. We're still awaiting some feedback about this issue, so the more examples we can gather the better.

Yeah that sounds good in terms of IP passthrough, if you find any settings changes that bypass the issue this may help the Service Desks that are working on this.

Thanks,
Jonathan

Hi everyone,

Sorry for the delay in updates. We'll need to correlate the info on the community with your actual Three connections to look into this one further. I've sent everyone that's replied a PM so that a support team can verify your account, and pass some details onto our Technical teams and Service Desks.
