I have a server running behind SSL (https://es.content-index.oustatic.com:8443). We got a report from somebody that that SSL cert was bad:
However, it seems good on our end. I plugged it into to an ssl checker (https://www.sslshopper.com/ssl-checker.html#hostname=es.content-index.oustatic.com:8443) which shows that the certificate to be good.
Is there some misconfiguration, perhaps, on the client's machine? Why would his machine complain about the cert?
