    Issue

     

    You are trying to deploy a package or advanceAgent (How do you deploy an Advance Agent with Peer Only checked? )  with a delivery method configured for peer download only and deployment fails.

     

    • Standard networking test (telnet, netstat..) reveals no issue

     

    When you look at the Tmcclnt.xlg log file (How To: Enable XTrace Diagnostic Logging for the Ivanti EPM Core and Clients ), you observe that your target machine 172.30.100.142 has found no peers.
