Discovery of Redis server fails with message "Unable to connect to host: <hostname> port: <port number>".

Solution:
  • Check if Redis server is running in the host name specified.
  • Check if the port number given is correct. Check the redis.conf file for the given port number.
  • If the Redis server is running in authenticated mode, enable "Is Authentication required" and give the correct password.
