MongoDB compass can't connect MongoDB server

My company has a local MongoDB server, I can use MySQL workbench to connect it (through ODBC->BI Connector). But when I can’t use MongoDB compass to connect the same server (I use same connection parameter–server name, port, username and password. MongDB compass try to connect for several seconds and saying the connection closed). Any idear why?

@Bill_Yang1 ,

Compass can only connect directly to MongoDB and not to the bi connector port and host…
