Updated to chrome and noticed I couldn’t login to my own site.
That’s mostly not wrong, although the “this time” is. The cert has never been fully trusted by chrome, but I click through because I’m a bad person. This time, however, there was no option to do so.
I mean, yes, I set the HSTS header, but that was with the same cert that chrome is now insisting can’t be trusted. Why in the world would you permanently store “must have trusted cert” on the basis of an untrusted cert?
I suppose this warning is too late to save anyone, but you can clear HSTS sites if necessary via chrome://net-internals/#hsts.
