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.

Mine cleared up for a few days, then the connection went down, had to restart the router and bam all the connection issues back again.

This has started happening to me over the past few days. 
I'm using GL.iNet GL-X3000 and APN 3internet. 
Been with Three for home broadband for a few years and never had this problem until now.

Spoke too soon, the issue is back on a Three Business connection. 
Not as often but it has started happening this past 2-weeks on various different websites.
Still totally unacceptable.

Issue has now returned as of this evening...

The issue has gone away for me since yesterday. Anyone else experienced the same improvement?

I have periods where it gets better then just as quickly stops. I managed a whole day without issue a couple weeks ago.

[fashric]

Nope, still as bad as ever.

No change here - still lots of Github errors unless I connect to a VPN.

That has clearly been the case since the beginning. Just give us your money and take whatever service we provide. Not long before my contract is up but hopefully this stands as a warning to those looking to use three in future

Did any one ever receive a PM from @JonathanB about this issue? Has anyone had any feedback? I'm getting quite sick of this, as a software engineer working from home I tend to pull code from github.com, ghcr.io, and other sites quite often and lately it seems to be getting worse. I set up a script to attempt to pull a docker container until success every 30 min, and it took over 24hrs to eventually establish a connection and pull.

At this point the issue isn't intermittent, my broadband working is intermittent.
