Expired SSL Certificate help
« on: September 30, 2021, 05:26:21 PM »
I'm using an older Mac running 10.11.6. Today I started having a problem with a bunch of sites (including these forums, wikipedia and many others) where I would get a "Not Secure" error

NET::ERR_CERT_DATE_INVALID

I'm pretty sure the problem is linked to this certificate "DST Root CA X3" which looks to have expired this morning

I already made sure my computer had the latest update (for my OS) and restarted it.

Anyone have any ideas how to fix this?
