NET::ERR_CERT_VALIDITY_TOO_LONG



The server certificate has a validity period that is too long

When accessing your https site using Chrome you may receive the following errorsThis is caused by your SSL certificate having a validity period that is longer than 39 months.From 1st April 2015 certificates longer than 39 months are no longer being issued. They are also being phased out by browsers. Chrome has taken the lead in marking these certificates as having a validity period as too long and returning a hard fail. This should only apply to SSL certificates issued after 1st April 2015.The only solution is to re-issue your SSL certificate . Your new certificate will be truncated to 39 months and any remaining months will be lost.So far it is only Chrome that has chosen to implement this hard fail. No other browsers are currently affected.
