Getting logged out of ServiceDesk Plus after I installed Desktop Central

Getting logged out of ServiceDesk Plus after I installed Desktop Central

I just installed Desktop Central on the same server as our ServiceDesk Plus server. Using the latest version of both products. About every five minutes, I get logged out of SDP, but I remain logged in DC. Is this a bug or do I have something configured incorrectly? SDP uses port 8080 and DC uses 8020. Both use regular http. Thanks!
