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).

Hey @EDIflyer,
Sorry not quite sure what happened there. Might have been related to the same issue, or a temporary glitch. Total speculation here, but if the connection failed at the time of the PM sending the system maybe thought you were spamming me. 😅
I got your PM and yeah we should have the info required. Hopefully everyone else successfully makes contact and we can get their details added to the same fault report.
Thanks,
Jonathan

I've encountered the same issue, which has escalated notably in recent months. I tried different approaches, including changing web browsers, modifying SSL/TLS settings in about:config, and testing various DNS servers. My internet connection is established through a ZTE MU5001 (5G) router, directly connected via an ethernet cable. Notably, parental controls are disabled. This problem has also led to occasional difficulties in form submissions, causing the loss of work on multiple occasions.

So is anyone looking into this Three?

Agree. @JonathanB there's clearly multiple examples from different customers now - are you able to escalate this to senior technical colleagues to investigate?

I'm in the same situation (NR5103E, firmware V1.00(ACBJ.0)b14).
I've also seen the same intermittent errors for a few months. Initially I thought it was the browser (I was using Firefox; as someone mentioned, Chrome does some retrying and the problem is less obvious). Then I realised it happened on the command line and in other apps as well.
I believe it's the same issue mentioned here:
In that thread, the OP mentions that switching to 4G fixes the issue. I can report it works for me as well, though of course it cannot be a long-term solution.
While on 5G, the "Cellular Info" section in my router's UI reports NR5G-NSA as Access Technology, and a RSSI of -89.
I'm using the following one-liner to test; it uses Curl to connect to github.com 10 times, ignoring the output but printing any errors. I'm attaching a screenshot of its sample output.
for i in {1..10}; do curl -I --no-progress-meter -o /dev/null https://github.com || true; done;

Hello all. Likewise experiencing the same issue here.
I have been a three home broadband customer since April and have somewhat recently within the last maybe two months started experiencing this error. It is getting very frustrating as it seems to be occurring very frequently and more frequently than when it started.
I have a NR5103E routher with Firmware Version V1.00(ACBJ.0)b14.
It is certainly either a router issue or Three network issue, as I've experienced it on multiple devices (Linux, Android and Windows affected) both wifi and ethernet cable connected, and the same devices on other networks have never exhibited the error.
I've tried changing various settings on the router, like DNS, DOS Protection; but to no effect.

Same firmware same modem same problems here too. I work from home and this is causing a few issues, can it be looked into asap clearly an issue.

It's not an issue that I'm familiar with off hand. I do wonder if the router is significant or not.
Are either of you able to confirm if the issue happens on a Three mobile SIM? Any compatible phone you can test the router SIM in too?
This may help us narrow down if it's a Three Broadband, device specific, or general issue.
Thanks,
Jonathan

Hi All --
I've been using Home Broadband with a NR5103E router for less than 2 weeks and I'm having some issues.
From time to time, I'll get the error below in Firefox (also happens in Chrome but it retries automatically). For general browsing it is mostly annoying but I can live with that. However, it gets really frustrating when running servers locally that can't connect to remote services.
Things I've tried already:
- splitting 2.4 and 5
- connecting a separate router via cable
- using Google's DNS servers
Secure Connection Failed
An error occurred during a connection to www.skyscanner.net. PR_END_OF_FILE_ERROR
Error code: PR_END_OF_FILE_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.
Has anyone experienced this? Any ideas on what I could try?
Many thanks in advance!
ps: Current Firmware Version: V1.00(ACBJ.0)b14

I am experiencing it all the time, especially in the evening when I am using the internet at home most. Sometimes I need to force the refresh 3,4 times before the page loads up correctly.
I'm concidering leaving and switching to another broadband. I was very excited when I got this one but the constant error starts to testing my patience.
I live very close to the 5G masts and once the connection is established the internet is blazing fast, but it needs that push and plenty of services keep breaking because of that connection issue.
