iOS Cert errors

Question

All, 
 On week 1 of rolling out XG at home. I have configured my iOS devices to be "clientless" and thus do not need or have the certs from the XG. However, when I browse to various sites in Safari, I get a "Cannot Verify Server Identity" for random sites (e.g. the identity of xxx.fls.doubleclick.net cannot be verified). When I check the cert, it calls out Sophos SSL cert. I do not have HTTPS or HTTP inspection enabled for these devices. 
 Any ideas?

Hi Clay, 
 Could you confirm your Web filter policy applied to your IOS device ? I suspect the category advertisements is blocked. If so then the connection with the website was terminated and prompted you with a block page or a certificate error because XG is hosting such message.
