Trying to setup a built and working .Net Core 2.2 Web application on my system. Have installed Mongo DB 4.0.

Getting a run time error. Below is the exception thrown
 
{{System.TimeoutExceptionHResult=0x80131505Message=A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector

Have already tried appending '?connect=replicaSet' to the connection string as suggested here : https://groups.google.com/forum/#!topic/mongodb-csharp/O460OHiFjZs

 

Connection string:

{{"ConnectionStrings":

{"DefaultConnection": "mongodb://localhost:27017,localhost:27018/?rs=SpeQue"}
