DCNM-LAN 6.2(3) Discovery tasks failed

After trying since several days i did not come to a solution. I add for discovery in DCNM-LAN a Task with 2 defined Switches. Now i am facing the problem that after starting the task it stucks and the Task has no more Switches in the list and i cant start deep discovery or rediscovery failed with Device 0 error. I have a Oracle 11.2 on a Windows 2008 R2 Server and for DCNM i use the same Servertype as for the Oracle DB. Users on the Switches are authenticated by ACS 4.2 via Tacacs. I took a trace with wireshark on the DCNM Server and and what i can see is that the discovery process on the Switch take a log time until the discovery starts. Also DCNM Server trys to connect with http to the switch, which fails (no feature http-Server) and i also can see the SNMP Requests.

Any help will be appreciated
