Belgian Patrick Aussems started his reign at AFC Leopards with a 2-1 loss against Bandari at Mbaraki Stadium on Friday.
William Wadri scored a brace for the Dockers while Marvin Nabwire struck for Ingwe.
The hosts started the match on a high, putting their visitors under immense pressure.
Their good start paid dividends as Ugandan Wadri needed just five minutes to get the ball in the back of the net. It was a punishment for the 13-time league champions who started the match on a low.
It took Leopards time to settle and match the Dockers who looked hungry for more goals.
