Intermittent connection issues loading/changing site- secure connection failed/site can't be reached

EDIflyer · ‎10-22-2023

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.

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.

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

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

This has now been running for 6+ hours, looks like the web site errors have gone away:

The two fails where timeouts when I ran my system out of RAM.

Although I now have a new error where I've been unable to connect to a Google Colab instance all day, without using a VPN...

Have a dummies guide on how to do this and I'll set it for my own where I have the issues? 🙂

So I just had a slightly different test/problem likely from the same reason. A game I play, DCS World, had its first big update out today since I started having the problems, so went to run the DCS Updater, which is its own dedicated exe. This errored multiple times with the following message

The last few lines being the key thing - The only way I got the updater to work in the end was having to go to the games webpage to get the webpage to load first in the browser, before the updater would then finally run, where it it fine and currently downloading at around 600-700mbps

Midnight54 · ‎05-22-2024

To add to this, the way this game updates, when you buy a new module (which I did as was released today), the only way to then download the newly purchased module, is to launch the game, then select the new module (airplane) from the list, which then closes the game and relaunches the updater.....this then fails with the same error....multiple times, because of Three's stupid issues!!!

Luckily I managed to do a workaround to make it work but its far from ideal for people. I had to load the game, go to the update section in order to select the newly bought module. Before I pressed to download it, I then had to tab out, load up a web browser, fire up the games website to make sure it was loaded, quickly tab back to the game then tell it to download!!!

Three........please respond and fix this stuff.......For the guys affected please give updates, have you made any changes, or rolled back any changes made in some areas? A game aside, its ridiculous that I cant even do normal banking or online shopping without pages failing!!!!

AkiTaiyo · ‎05-22-2024

I had an outage on Three this morning at about 6AM.
Been running my test app for the past two hours (32 sites, 10s request intervals), 0 failures so far.. Has something changed?

EDIflyer · ‎05-22-2024

Very interesting - that fits a bit with the experience I had last week of an outage and then the system working afterwards without errors!
