Event Handler domain status updated is not calling my sh script

When setting up an Event Handler of the Domain status updated event my script is not called. In the Action Log are events visible that should be the Domain status udpated event.:

Under Domains -> Set from Active to Suspend:

XXX.XXX.XXX.XXX admin-user [2016-10-28 16:40:50] 'Update Domain Status' ('Client GUID': 'f3babb69-f179-432b-aa2a-c91aeabb31d1' => 'f3babb69-f179-432b-aa2a-c91aeabb31d1', 'Domain GUID': '18e9aac9-ec26-427f-86a8-18da4ba4fc90' => '18e9aac9-ec26-427f-86a8-18da4ba4fc90',...
