No RFC authorization for function module RFCPING

Hello guys,

I have created a system and while testing the system I am getting the following error. Please help me solve this issue.

"No connection to system s51 found:

com.sapportals.connector.connection.ConnectionFailedException: Connection Failed: A nested exception occurred. Could not initialize physical connection.

Connection Failed: A nested exception occurred. Could not initialize physical connection.
