No problem. I have probably been troubleshooting connectivity on the web for longer than most people on this site have been using it

Soooo ahem obviously I totally know what that all means but for the other guys who don't have that knowlege can you explain in leymans terms

Sure. That's how the negotiation to upgrade to TLS (transport layer security, or "https") happens. Curl is a command line web-browsing tool often used to provide insight into what is happening under the hood. Running it in verbose mode (-vvv) gives you chapter and verse. For me it's working fine. The output from some device that's not working _might_ shed some light on why it's not working.

One Q for those experiencing problems - when did you last get updates on your device ?

I don’t know but not that long ago so maybe a few days before my ‘outage.’

It has changed my private browsing settings ( don’t ask) after updates before and that’s reset itself after a couple of days.

So if you've had recent updates, and applied them, and the time is correct on your device, then we've ruled out about 1% of the possible causes

Are admins running fail2ban or any such adaptive blocker ?
Have network operators incorrectly configured some transparent proxy ?

Android users could install f-droid / termux and run the curl command (see exact syntax in my earlier pastebin link) to help troubleshoot further.

This sounds like a network problem. Virgin Mobile uses the Three cellular network...

digitalscream · October 2021

The most obvious explanation is that there's something about the SSL cert we're using (or a cert in the chain) which is tripping up on the Three network.

I can verify that it's definitely working on EE and Vodafone.

I can't imagine that the site itself is explicitly blocked by their network - we're just not big enough for them to take notice. In the absence of another explanation, I'm going with that. However, I can't offer a fix, because I'm not about to buy another (more expensive) certificate for such a small use case. Sorry

TLS negotiation is between the server and the end device (it is designed to prevent man-in-the-middle attacks), so hard to see that a new certificate would fix it. It's a mystery for sure. Very unlikely to be a problem on the server end given the small number of reports, and the common factor of mobile devices on mobile networks.

If any affected fretboarders on Android could install f-droid / termux I'd be happy to talk them through providing more diagnostic information.

Same for me too, also on three

If admin arnt bothered with looking into this then I'm certainly not going to dig any further, it's one website out of the entire Web I can live with that, thanks for your help.

Seems to be quite network specific.

I can't see FB closing accounts. Close them why? It sounds to me like network provider issues

No problems on an iPhone on ID which uses the three network.

Nothing to do with closing accounts bud, its Website specific,

Nooo...he means it's closing the network connection early, in the middle of the encryption negotiation between the device and our server.

Got you

It's working for me again now
