3.2 Problem with Safari browser

I'm using nop 3.2 with SSL certificate. Site works fine in all browsers except Safari.
Every time safari switch to https protocol message pop up with "No certificate available"

I have another site with nop3.1 with same kind of certificate and Safari browser works fine.

I think you should address this question to your certificate authority

thanks Andrew,
I talked to Geo Trust and the clime that certificate is ok and install property and give me link.

did anybody else experiencing same issue?

Anyway, it's not related to nopCommerce somehow. Only certificate authority can help you with it. You can also try reaching Safari support team
