Answer 1

I had the same issue. I was able to connect to MongoDB Atlas Using MongoDb Compass, but using the same connection string in a C# project I got the error "A timeout occured after 30000ms selecting a server using CompositeServerSelector... ---> System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (61): Connection refused 192.168.1.254:53".

In my case the problem was caused by my Internet provider router. Switching the connection to my iPhone's 4G hotspot solved the connection issue.
