main.CRITICAL: LOADING Redis is loading the dataset in memory

Hi Craig, I followed your guide and thank you so much for it.
Now after going live in production environment, the website from time to time stops responding for longer intervals and than load with no css or js. After debugging for a while, I noticed that Redis was the problem. If I go to redis-cli and than flushall the website starts working for a while. I was wondering if you could help with it.

Here’s the log from exception.log:

[2021-11-09 22:23:08] main.CRITICAL: Connection to Redis 127.0.0.1:6379 failed after 2 failures.Last Error : (111) Connection refused {“exception”:"[object] (CredisException(code: 0): Connection to Redis 127.0.0.1:6379 failed after 2 failures.Last Error : (111) Connection refused at /var/www/html/vendor/colinmollenhour/credis/Client.php:493)"} []
