I am getting ORA-12570: Network Session: Unexpected packet read error when connecting to an oracle database from asp.net application.
Error Frequency: Not consistent and works fine one time and throws error next time
Environment Detail Oracle Managed Data Access v12.2.1100 Visual Studio 2015 Oracle Database 12c Enterprise Edition
Error Stack Trace Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> Oracle.ManagedDataAccess.Client.OracleException (0x80004005): ORA-12570: Network Session: Unexpected packet read error ---> OracleInternal.Network.NetworkException (0x80004005): ORA-12570: Network Session: Unexpected packet read error ---> System.Net.Sockets.SocketException (0x80004005): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
I would appreciate any solution to this issue as it is difficult to figure out myself and tried changing code but no help.
