Hi

On one of my servers I installed mongodb 4.2 and by default TLS is disable and I give access to all ip address to connect to my mongodb database but every time I try to connect to this server based on port 27017 by robo I face this error:

Error:
Network is unreachable. Reason: network error while attempting to run command 'isMaster' on host

And whenever I try to connect by asp.net core i see this error

TimeoutException: A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }. Client view of cluster state is { ClusterId : "1", ConnectionMode : "Automatic", Type : "Unknown", State : "Disconnected", Servers : [{ ServerId: "{ ClusterId : 1, EndPoint :

But when I use VPN ,connection to my server is successful even without VPN I see connection listener in log file but without client metadata . I do not know what is the problem even I give access to all ip address.

please help me to solve the problem.
