NET::ERR_CERT_DATE_INVALID suddenly happening on Chromium browsers?

[tdd]

Hi all!

I use a devcert-based tool of mine to set up TLS certs on my dev machine so I can do HTTPS development.

It's been working swell until very recently.

Suddenly I get NET::ERR_CERT_DATE_INVALID errors on my .test local domains, but only on Chromium browsers. This is unfathomable, as inspecting the certs in these browsers shows a valid date range:

• NBF Dec 2021
• EXP Dec 2023

I have no idea what gives, but in the meantime I'd like to just remove that cert from my devbox and have a fresh run regen it, but I have no idea how to remove a cert installed by devcert.

Any pointers?

Thanks!
