Myndex / SAPC-APCA

APCA (Accessible Perceptual Contrast Algorithm) is a new method for predicting contrast for use in emerging web standards (WCAG 3) for determining readability contrast. APCA is derived form the SAPC (S-LUV Advanced Predictive Color) which is an accessibility-oriented color appearance model designed for self-illuminated displays.

www.myndex.com has an expired cert #91

Closed Seirdy closed 1 year ago

Seirdy commented 1 year ago

Does this relate to a web app or tool (i.e. you're an end user) OR is this about code or code integration (you're a developer).

This relates to the https://www.myindex.com website

Describe the bug

The website https://www.myndex.com, containing the APCA calculator web app, has an expired TLS certificate. The certificate expired on the 24th.

To Reproduce

Visit https://www.myndex.com/APCA/ in a modern browser, or run curl https://www.myndex.com/APCA/.

Expected behavior

The website loads.

This behavior is device- and OS-independent; it appears in any correct implementation of webpki.

AH nuts!! The update script must have some issue... Thanks @Seirdy will correct it ASAP, thank you for letting me know!

Myndex commented 1 year ago

Well this problem is deeper than I thought... something with the LetsEncrypt cert chain is totally borked... UGH... suggestions welcome.

Seirdy commented 1 year ago

There's always the option of requesting a totally new cert instead of renewing an existing one, or switching CA providers entirely (ZeroSSL offers free certs through the ACME protocol, just like LE). You'll need to update your server configs to point the new certificate path, or replace the old certificate path.

Well, that was a really annoying bug to chase down. Closed as corrected. Resolution is discussed at LetsEncrypt.
