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.

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?

So far the only ways to get around these issues are to use a VPN or Cloudflare's WARP - Your websites do work for myself when using WARP

As for how close are Three to fixing these issues, we have no idea - The Three or so members of the support team have not kept us updated here although there has been some tracing session progress going on lately

Just a quick check-in on the state of things

Have there been any changes for you all? From my end, some things are a touch more unstable than before when not using WARP

No change here either, still seeing the same random pages failing to load.  Also noted that in Xbox when I try and start Diablo IV I can never connect to the battle.net servers on the very first attempt - it fails almost all the time (I think I've seen it load on the first go maybe twice in 50 attempts) - but always connects without fail on the second attempt.  I wouldn't be surprised if this was something to do with the issue here.

I remember seeing the issue rear it's head when I tried to login to the battle.net site in a desktop browser as well (and as I speak I tried it just this minute (loading battle.net) and I've got the usual PR_END_OF_FILE_ERROR error).

Similar. A few docker images and Home Assistant wouldn't up date, after a speed test on a different device and a third attempt they magically started working.

A new month begins and the issues are still there for myself at least

Have there been any changes for any of you all?

Maybe this will be the month when everything gets fixed?

I had another tracing session with Three yesterday. This time they had a number of scenarios to run through.

I'm cautiously optimistic that they are getting closer to the root cause. I didn't get a timeline, but they said they would get back to me once they've analysed the data collected.

I haven't seen any change in the issues - it's been remarkably consistent for me over the last few months.

Thank you for you time on sessions with Three and your updates on what is happening, you do us all a great service! ⭐

Still seeing issues here as well, noticed issues on the Morrisons app today when trying to checkout and the app would fail telling me I wasn't connected to the internet but a tap on the 'try again' link would instantly take me through OK.

Various pages in Firefox on Android on my phone failing to load but again with a refresh they instantly load OK.

it happens far less often for me than it used to, and I was able to update Home Assistant without issue today.
