MongoDB C# 2.0 TimeoutException during using findAll()

Question

I HAVE THIS PROBLEM:

A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = WritableServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }.

        var conString = "mongodb://172.16.1.24:27017";

        var server = client.GetServer();
        var database = server.GetDatabase("knjigoMata");
