I installed SSL certificate of Let’s Encrypt by using commands in October 2019 on AWS EC2 user for a site (http://powerlinehardware.com/). Now on 21st january, 2020 is certificate is expired. I got a guide of how we can renew this certificate. It said that we can do that by switching to sudo user by sudo -i and editing crontab by crontab -e and then adding this line: 30 2 * * Sun /home/ec2-user/certbot-auto renew to renew it on every Sunday and 2.30am. But it did not work.
So the site is experiencing security error. Please help us regarding this because it is a live shopping site and it has to be https.
