Uncaught Predis\Connection\ConnectionException: Error while reading

Installed the plugin and the status shows it is connected.
PHP Version: 7.1.4
Multisite: No
Redis: Not Found
Predis: 1.1.1
Status: Connected
Client: Predis (v1.1.1)
WP_REDIS_CLIENT: “predis”
WP_REDIS_HOST: “127.0.0.1”
WP_CACHE_KEY_SALT: “”
Drop-in: Valid

But the errorlog keeps generating errors…..
What could be the reason for this behaviour?
Shot from the errorlog :
