Cannot connect on-premise gateway with postgres on PowerBI

[ramin]

With powerbi desktop I can easily connect with postgres database on server(192.168.1.5:32100) running on a port and a database_name. But doing the same with PowerBI on premise gateway I could not connect when adding a data source on gateway setting(gateway cluster). Below screenshot for reference. The first picture is of PowerBI desktop and the second one is on gateway settings. Is it something with the port?If yes I was able to connect on PowerBI desktop, if no then is there any way or am I missing something. Thanks in advance for the help.

Is the appropriate PostGres driver installed on the gateway machine?
