No Start OpenHAB-2.1.0.002-SNAPSHOT --> DSM 6.0.2-8451 Update 9 auf einer DS716+

I have created the following machine DSM 6.0.2-8451 Update 9 on a DS716 + and these folders:
Variant 1 - public / @appstore / openHAB2 / conf
Variant 2 - public / openHAB2 / conf
Variant 3 - home / @appstore / openHAB2 / conf
Variant 4 - home / openHAB2 / conf
I also installed JAVA SE Embedded 1.8.0_121-0043.

Then I installed [OpenHAB-2.1.0.002-SNAPSHOT-DSM6-syno-noarch-0.001.spk]

Then I start the URL http://192.168.178.2:8080/start/index

The result is “Firefox can not connect to the server under 192.168.178.2:8080.”

Can someone help me? What did I do wrong???
