RedisException Connection Refused

Im new to programming. I have an aws ec2 instance which was working fine...

I have a laravel project on it. I use Ubuntu and Apache2 on aws ec2 instance.

I rebooted instance from aws. When it comes online, i had default apache2 page like this;

default apache2 page

After that i edited /etc/apache2/sites-available/000-default.conf file from;

DocumentRoot /var/www/html

to;

DocumentRoot /var/www/merit/public

where my project is on.

After that it started to come up with this error;

RedisException - Connection refused

error

i didn't make any changes on .env file and i do not use redis neither.

What is the problem. Anyone can help or anyone got an idea?

Thanks in advance
