I have web filtering enabled, the Personal Network Storage category is allowed, and testing the usden-edge.icloud-content.com domain in the Policy Test tool is approved. However, when I try to send messages via iMessage in the Messages app I get this:
2016:11:29-20:02:41 gw httpproxy[5486]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="PUT" srcip="192.168.1.36" dstip="17.248.133.169" user="" group="" ad_domain="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_HttCffParenFilte (Protection Filter Action)" size="2795" request="0x14e80400" url="usden-edge.icloud-content.com/D2xwoVEBWLMvJbICoOpq referer="" error="Received invalid request from client" authtime="0" dnstime="643" cattime="289" avscantime="0" fullreqtime="4685" device="0" auth="0" ua="IMTransferAgent/1000 CFNetwork/807.1.3 Darwin/16.1.0 (x86_64)" exceptions="" category="170" reputation="unverified" categoryname="Personal Network Storage"
error="Received invalid request from client" is the concerning part. I'd be fine bypassing the proxy for these requests, but usden-edge.icloud-content.com resolves to multiple IP addresses via DNS round-robin, and the DNS group only picks up one IP address when I add it.
Is there another way to let these requests bypass the proxy, or even better, see what's going on with the invalid client request and fix it?
Thanks!
