Solution for this Error is:

Reason : Entry in tnsnames.ora syntax is incorrect or missing some parameters.

Solution : 

Check the below syntax is matching according to your SID(TEST) , IP Address(192.168.75.131) and Port (1521)

otherwise copy this below syntax and paste in your $ORACLE_HOME/network/tnsnames.ora

and change these SID,IP and Port according to your Env.

TEST =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.75.131)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = TEST)
    )
  )

 After doing this you can verify it whether this is ping or not using tnsping 

C:\Users> tnsping TEST
