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.

Just another weekly check-in to see how things are for you all

I have not noticed any major changes

Intermittently (ie at present) it seems to be OK for me.  I'm loathed to say it's fixed because I'm sure in another day or two the problem will probably be back again.  Really seems to me like it's some kind of intermittent issue to do with which of their servers does your packet inspection and if you get a dodgy one then the dropped packet issue (if that's what it is, seems that way?) starts kicking in.

Sometimes when I get reassigned a different IP address after being reconnected for whatever reason the problem just magically disappears.  Then I'll get reconnected again later and the problem comes back.  Presuming you're assigned a certain 'route' through the Three network (ie for packet inspection) at the point that you reconnect to the service (ie get a new IP address etc) then you're stuck with the problem until you reconnect again.

Lot of presumption...

Maybe with that Cloudstrike issue last week some of their boxen went down and they had to reboot and it's magically fixed the issue though eh?!

EDIT: having said above it was OK at the moment, I've now had the PR end of file SSL thing pop again on Morrisons grrr

Yep no change for me at all, some days far worse than others - and the same typical thing on trying to run games own updates (that dont use Steam)

Where I have to launch the website, get it eventually working then quickly run the updater as fast as possible.......realdebrid downloads still very much broken outside of using download managers......out of curiosity I tried to download a 5mb file using Chrome on Real-Debrid (where Chrome just looks) - 50gb later it was still going on repeat back to the start again every time! (vs Firefox which can hit retry a couple of times at the end of file and it will complete without restarting

Same.  Still seeing regular SSL errors.

Also had issues with downloading packages using PIP and APT since I've been setting up some new systems.  Often see them either quit out dues to failed SSL or occasionally the download just gets cut off partway and fails.  Doesn't happen when using a VPN..

Come on Three, fix your broken network!  Or at least give us a $10 uber eats voucher 🤣

Yep, same here, still good days and bad. I have major issues logging into Microsoft through the Xbox app on pc, sometimes it will take me 5+ attempts at logging in before it works. Some sites I use will still throw up the connection error regularly too. Thought they would have made at least some progress with this by now.

I've not been doing much browsing lately head down working or streaming video. only issue I noticed is the massive lag spikes even though the router appears to have good 5g signal. My HA and related services have been updating okay but I don't update them as often as this issue caused it to be such a headache.

Hi everyone,

As @toaster mentioned, we've ran a couple of live tracing sessions to get data over to the engineers investigating this. We're hoping to gather some more live data on Monday 15th. Is anyone able to help with this please?

Ideally you'd need to be free for an hour some point between 1000-1700, and we'll gather info on your line whilst you trigger the errors. Please reply or PM me your available times if you'd like to take part.

Thanks,
Jonathan

If its any use, I have a small web (streamlit) app making use of an old Raspberry PI.  This would allow your network engineers attempt to trigger the SSL errors when they wanted, without needing anyone else 'on the line'..  PM/reply if you think this would be useful and I can provide access information.
On a button press it runs though a list of pre-defined URLs and reports if any errors occur.

This is running from my own Three connection.  Currently, I don't think I'm getting as many errors as other users though.

I missed all of this because I was away 😔

If you still need someone to visit many random websites then I can help with that

It is great to hear something more official after a long time

I found this thread since I'm having problems connecting to an FTP Server using TLS. It just won't work 😞

I then hit a problem trying to use an API call, which again just refuses to work from within my network. Doing various tests it looks like SSL/TLS is being blocked which I think is a related issue, similar to my FTP TLS this morning.

I do love the cost and speed of my Three 5G Hub, but some of these issues might just push me back to a connected line internet service 😞

I have also had connection issues to various sites I use, which have been happening since I started the 5G service. These include Screwfix.co.uk, https://www.hl.co.uk/ and Santander.

How close are we (well Three actually) really to actually resolving these issues?
