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 may not be with Three formally yet I can still use the same APNs as the other Three MVNOs - As far as I am concerned, all of them are affected by the same issue

If you have any connections or contacts that can reach the other MVNOs, please do what you can to alert them of this issue as they might be able to help and, at the very least, they should be able to reach more people suffering from these issues

If you would like a list of various websites mentioned in this thread which often trigger the PR_END_OF_FILE_ERROR, let us know as they are buried within the 44 pages however, the issue is not limited to just those websites

Hopefully there will be a solution found sooner rather than never

Thank you for your reply and hopefully there will be more regular updates at least once a week to mention what is happening - Your last response is on Page 42 but that was Three weeks ago

Still failing randomly on some sites here.  Noticed it on Wikipedia yesterday.  On Mozilla Firefox on Android there's no mention of the PR end of file error, it just seems to stubbornly not load the page with a 'Try Again' error.

Just a check-in

No changes however yesterday was quite bad for a random test - Websites would fail then work, fail then work, on and off for several hours...

How bad was bad? If I had that level of website failures on my first day of switching to Three, I would have left immediately with no regrets and there would have been no possibility of staying even with a negotiation

Three, consider yourselves lucky that this widespread problem can, and does, vary in severity at random

Interesting, I also experienced increased failures on sites I visit frequently the last couple days.

I haven't had any of the PR_END_OF_FILE_ERROR recently but maybe it's because I've set the APN as Three.co.uk and IPV4 only. I've also setup the hub in bridgemode with all the routing being done by my Zenwifi XT8 mesh.

I do have an issue with the Cahoot bank website where it logs me out constanly when I trying to change email and phone number settings. The same website works perfectly fine when using a London VPN.

From my experience, the three.co.uk APN was more stable and did not support IPv6 compared with the 3internet APN

Setting up your other router to do the routing probably helps as it would not be enforcing any of Three's routing agendas (Speculative point)

Unfortunately I can not test Cahoot bank as I have no account with them however did the website ever work with just the Three provided router?

Does anyone use Twitter (I don't) and have a lot of followers? It may be worth calling Three out directly and referencing this thread. Companies seem to respond more when they are very visibly publicly shamed, and clearly this thread is getting nowhere.

Just another message checking in on the state of things for everyone

Today I started my testing by turning off WARP and going through the list of websites that usually cause issues however I did not get very far - https://duckduckgo.com/ caused the PR_END_OF_FILE_ERROR to appear immediately and, less than a minute later, https://en.wikipedia.org/wiki/Main_Page caused the same issue on a page refresh

I guess it is safe to say that the issue still persists.............

Frustratingly so and tumbleweed from Three.  Sometimes having to refresh pages 10x to get them to load its that bad some days

[torz77]

There is no issue. Nothing to see here. Just because you think there is an issue, doesn't mean there is one. We'll keep taking your money in the meantime.

Given the total lack of any kind of progress or recognition, I'm going to vote with my wallet, and am looking for alternatives.
