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.

No change here though issues do seem less frequent. Ironically the only issue I had today was the EOF while trying to get to ProtonVPN to set up a new virtual machine for testing

After installing linux to windows and trying @wgen s script, most sites are passing the test (only 1 I know of that is failing - however the issue is definitely still there as getting some pages still failing to load - it is fairly late however so maybe increases the success rate.  I also tried a debrid file download and still getting exact same issue (chrome loops forever downloading from start, reports Failed if use Firefox at end of file but hit retry several times and it eventually says complete (without redownloading the whole thing)

Will try to test more tomorrow evening

I'm still seeing a lot of issues. I'm mostly struck by the range of sites affected (amazon, wikipedia, IMDB, steam, AWS S3, facebook, github) and how variable things are for individual sites.

e.g.:

  • Failed connections to Wordpress,org have gone from not really appearing on the 19th/20th to failing nearly 50% of the time last night!
  • Connections to my test server fail anywhere from 0%-2.6% of the time

Out of the 114 test sites, sometimes only 8 sites (~7%) are affected during a test (~7 hours) - othertimes up to 20 sites (~18%) are affected.

So after thinking things were going well (no issues for the past few days), I then had issues accessing web.archive.org today.  I was getting the usual "unable to provide secure connection" message -

Switching on a VPN fixed the issue as usual.

When I switched the VPN off I then got a different error:

However I had already disabled content filtering previously, about a year ago!

I therefore went into plan settings and indeed the "Allow Adult Content" option was indeed off. I switched it back on, provided a credit card number and received a text confirming it had been set:

I then tried again in a fresh browser - same error - however when I go back into my account the filtering is definitely disabled and adult content is allowed:

I'm not sure what is going on but sadly after getting my hopes up it is definitely not fixed!

At first I thought the script wasn't picking it up as it showed success, but I realised I had just put in "web.archive.org". Changing it to "https://web.archive.org" showed 20/20 errors...

This may be due to Threes adult content filter.. I've just tried archive.org and found out they have turned mine back on..
Requesting the http version redirects correctly and returns a correct status code 200, but from the wrong URL..

Interestingly, this is redirecting even though my setting is set to allow adult content..

I think the adult content switch on the plan page is a whole other bug as I was able to view adult content, check the switch and it said that it was off. So I toggled it on, and still able to view it.
