Title: Plusnet and TLS
Post by: Alex Atkin UK on April 13, 2021, 09:11:29 PM
[Moderator note: This topic has been created by splitting the following posts off of bob.gas' Plusnet bill? (https://forum.kitz.co.uk/index.php/topic,25796.0.html) topic.]

They still haven't fixed portal.plus.net using outdated TLS 1.2 either.

Totally ironic when that needs to be more secure than the community forum that DOES support TLS 1.3.

Currently my Billing page says "There has been an issue; please consult your system administrator" LOL.  Touch wood, so far I haven't had any billing issues.

Portal website is managed by Plusnet, community forum isn't  :)

TLS 1.2 is perfectly fine to use I can certainly understand them still having it enabled, a commercial business cant have large swathes of their customer base unable to connect to the portal.  However they could probably start supporting TLS 1.3 for clients that support it, maybe they wary that its not mature enough as  a tech yet to trust it to work properly.

Enabled yes, but Firefox have deprecated it by default so the page wont load at all.

The idea is TLS 1.2 is enabled for legacy browser support, there should absolutely not be any situation where a modern browser fails to work because TLS 1.3 hasn't been enabled.  I can't think of a single other site which fails to work in Firefox.

Problem is not everyone runs an up to date client, Firefox probably have jumped the gun a bit though by disabling 1.2 by default, is a lot of sites that dont support 1.3 yet.  Its far from widespread in terms of adoption.

Hmm are you sure you didnt tinker with 1.2? This page indicates they only deprecated 1.0 and 1.1.

Seems they also had to back out on tls 1.0 as well due to some government website's not even using 1.2 yet.

I think I misunderstood and its not TLS 1.2 specifically or Firefox itself but something about the specific certificate they use and changes in my OS. https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2

Looking at the certificate fields in Chrome I can't figure why it trips up in Firefox though as both certificates seem to be 2048 in size using SHA-256, so either both should work or neither should.  ???  I must be missing something or its a bug.

Hmm yeah they need to update that, it kind of reminds me of the email server issues they had that never got resolved for long periods of time.  A company where its priorities have all been sucked into sales.
