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.

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.

Have any of you started getting crazy lag spikes recently? 500-2000ms

I would have just said it was just the connection to the tower but recently it seems worse and its happening consistently when my kids start a match In Brawl Stars. Then it will be okay for several minutes then happen again.

Do we think this is tangentially related or not?

It probably is related as any packet alteration methods in use would increase latencies

The specific docker repositories I have the most difficulty with are ghcr.io and linux.io - not their http counterparts but pulling the image files themselves. Anybody else having this issue?

Yep, lots of us unfortunately - OK when connected to a VPN though.

This is a know issue vector, you'll see myself and many others also have the same issue pulling docker images from those domains.
