Such servers typically use two different ports: one for establishing a connection and the other, referred to as QueryPort, for retrieving server information.
If you enter only the connection port and encounter an error message stating that the connection to the server cannot be established, it may mean that you also need to specify the QueryPort. Typically, the QueryPort value is the connection port value +1. For example, if your server's port is 26900, then the QueryPort is likely to be 26901.
