Question SSL Problem - Server Certificate

[TobiasGo]

Hi,

on ssl labs, certificates are degraded to B in case of a problem with the server certificate:

SSL Server Test: speedit.org (Powered by Qualys SSL Labs)

www.ssllabs.com

The Certificate in #2 is outdated since 2 yeas and 3 months.

How to update this certificate?

Or is it possible to deactivate this Server Certificate?
On SSLLabs it is a problem, with the second certificate, in case of missmatch in servername.
