CRRDG7801E Debug connection to remote_IP_address could not be established using an unsecured socket.
A possible cause is that the Debug Manager is running in secured mode, but the Remote System Explorer connection is not secured.

Explanation

An unsecured connection could not be established with the Debug Manager because the Debug Manager was running in secured mode, but the Remote System Explorer connection was not secured.

System action

Connection is not established.

User response

Configure the Remote System Explorer connection and the Debug Manager to have the same level security, or use the IBM z/OS Debugger preferences page to configure the secure settings. For more information, see Preparing to debug for an Eclipse IDE.
