It's using a SHA-1 certificate hash, which many browsers now reject on recently-issued certificates as the algorithm has been proven weak. https://security.googleblog.com/2016/11/sha-1-certificates-in-chrome.html https://social.technet.microsoft.com/wiki/contents/articles/32288.windows-enforcement-of-sha1-certificates.aspx#February_TwentySeventeen_Plan https://blog.mozilla.org/security/2015/10/20/continuing-to-phase-out-sha-1-certificates/ Jan 2017 was the cut-off date most agreed on for any certificates. It needs a new cert in June anyway, so might as well get the upgrade over and done with early! :-) Cheers, James Harrison
