SSL Certificate and incomplete chain Support Center plus

SSL Certificate and incomplete chain Support Center plus

Hello,

we configured Support Center plus to use a globalsign wildcard certificate. (pfx-file in config, server.xml modified)
The site works fine with SSL, certificate states no errors.

But when we check our URL with SSL Labs we only get a B rating because the certificate chain is incomplete. Caused by a missing intermediate cerificate.

How can we fix this ? If I check the certificate, certification path is see the root, intermediate and domain certificates without any problem.

Kind regards,
