Hello
This is nice to know for all (I guess) customers using the Apache Web server as a reverse proxy for storing and distributing definitions to MAC clients. Since 2015 april 18 the MAC clients stopped getting new definitions. Turns out that the "hard coded" LiveUpdate URL (liveupdate.symantecliveupdate.com) in the httpd.conf is invalid since that day. Stopping the SEPM services and changing the address to liveupdate.symantec.com and starting the services again seems to do the trick...
