Having an odd issue with Yosemite Server's Caching service. When I enable it in Server.app, it says "There was an error communicating with the remote content server." In Console, I see the error comes down to... Code: 9/24/15 11:46:56.123 AM AssetCache: Request for registration from https://lcdn-registration.apple.com/lcdn/register failed: HTTP response 400, body "INVALID_DEVICE" I unfortunately am tunneling all internet connections through zScaler cloud security. However, *.apple.com has been whitelisted and is exempt from authentication and SSL inspection. So it shouldn't interfere unless Apple doesn't like zScaler's public IP address. I found a semi-related thread on MR, and the solution was to set the caching service's interface from Terminal. I did try that by running "sudo serveradmin settings caching:Interface = bond0," but no dice. Any other suggestions?
