I installed redis on my server. I am unable to connect to server with ip address but able to connect with localhost. I am unable to connect to this redis from other servers too. What could be the reason?

Try to change bind IP
Go to the redis file location and open the Redis configuration file with a text editor
sudo nano /etc/redis/redis.conf
change bind IP (you can use allowed need IP also)
