PHP warning in last version

After I have updated my WordPress and Redis plugin, I am getting this error. Do you know tell me what is it? Is it really an issue in the last plugins version or should I do something in my server? Tks! ??

RedisException: read error on connection to localhost:6379 in /wp-content/object-cache.php:2148
