Just what the title says I tried cs.rin.ru, fitgirlrepack and a whole lot of others who are legit but bad certificate. Why?
Check your system time, if it’s wrong certs go bad.
Nah and it’s automaticaly sinchronized
Can it be because I updated the certificate of a website I am developing?
On your local system? In that case yeah, you might have fucked something up, if you for example replaced a root certificate authority or something.
SSL_ERROR_BAD_CERT_DOMAIN means incorrect SAN information, proxying, or DNS manipulation is occurring. You could compare what you see in the browser and what you see via something like:
$ openssl s_client -showcerts -connect cs.rin.ru:443You could also check the DNS resolution and traceroute to see how you are getting there to confirm if DNS is being effected or you are being proxied:
$ dig cs.rin.ru @127.0.0.1 A$ mtr cs.rin.ru
