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.

With AkiTaiyo's help, modified the other script slightly and ran it last several minutes, ssl errors being logged successfullly now.  Reddit for most part returns failures for some reason, but still gets SSL errors once in a while.  I suspect that if I increase the delay between each check that the SSL errors might increase

Mostly been working over VPN today as had lot of work to do so not tested much of actual real life browsing, but the issue is definitely still there

Increased the RequestInterval from 500 to 5000 to slow down between checks, and real-debrid is significantly worse for SSL failures right now - with 21 out of 44 requests SSL erroring, and 9 out of 44 so far for Santander

After running for some time with the much larger delay, almost 50% failure for SSLs on real-debrid.  Santander seems to have waves where it gets several failures then is ok for a while.

wikipedia I noticed shows there fine on each test, but I accidentally clicked a google result that was a wiki link and actually had the error in the browser, so the errors are still actually there but not captured

Out of interest are others having issues with The Internet Archive? 

For insecure (http://web.archive.org) I get the 3 Content Blocker message, for secure (https://web.archive.org) I get the usual ERR_SSL_PROTOCOL_ERROR 100% of the time.

In browser web.archive.org is working for me.  I'll add it to the checker that I'm running.  Current update on that is approx 40% SSL failures on realdebrid by tar the worst performing.

Probably reddit after that with a mix of SSLerrors and timeouts, then pinterest and Santander.  This is with the 10x longer delay so has been over quite a period of time

Seems really bad again for me again today after about a week of very minimal issues.

I can't even do my Santander banking changing between pages cos the pages are constantly bombing out either with either the "retail.santander.co.uk unexpectedly closed the connection." or it bombing me back to the login screen that I have to go to my parents home to do it!!!  Three / @JonathanB please when can this issue be sorted, its causing me huge issues with doing simple but important things such as banking, let along the damn inconveniences its causing between multiple websites.  Why has there been no updates when this is a big problem!!!!!!

If anyone is interested, I've made my app+source available. 
It's hacked together in C# so feel free to make improvements on it.  Requires .net8 to run the binary.  Tries to categorize most of the errors (in a really dodgy way).
Gives you a readout like this on the console window, press "esc" to stop it running, but it doesn't save the results so you will want to copy/paste them to somewhere before closing the window!
