Is this problem happening on Windows clients only?
Could you try add the Entrust Subordinate Certificate L1K to your the certificate trust lists on Windows machines, see screenshot on link ?
To do this, download the certificate from here  and from a machine running Windows run certmgr.msc and add the certificate in here: Trusted Root Certification Authorities > Certificates
