Hi, I have an SSL error in my browser (Firefox 53.0.3 x64): Secure Connection Failed. An error occurred during a connection to maicol07.tk. Peer's Certificate has been revoked. Error code: sec_error_revoked_certificate With the other browsers it works. Why? I see also that the certificate (issued by ZeroSSL) has expiring date on 2020! The others certificates by ZeroSSL of susbdomains has all expiring date on 07/2017... Thanks
