When I try to access my oracle instance using basic connection type. It gives me an error telling "The network adopter could not be able to establish the connection", But I can connect to the same user using TNS connection. What is wrong? As I guess it is not my oracle instance in the default 1521 port number.

If you know SID run TNSPing util
tnsping sid
and it will show you this info
