staus: Failure - Test Failed: IO Error: Got minus one from a read call Error

While connecting the database through sql developer got error,

"staus: Failure - Test Failed: IO Error: Got minus one from a read call"

Solution:

set "tcp.validnode_checking = no" or comment this parameter in sqlnet.ora file then restart listener on db server and test again.
