    I usually use the command below:

    sudo certbot renew --dry-run

    After running command above, you can check the status of SSL by using the command:

    sudo systemctl status certbot.timer

    Below is the result:

    certbot.timer - Run certbot twice daily
   Loaded: loaded (/lib/systemd/system/certbot.timer; enabled; vendor preset: enabled)
   Active: active (waiting) since Tue 2021-02-09 21:38:50 UTC; 9 months 0 days ago
  Trigger: Thu 2021-11-11 09:24:49 UTC; 5h 20min left

    I found a solution very easily. You can run the command below on your Linux server:

    letsencrypt --nginx renew

     And you can see the result as below:

    The following certs were successfully renewed:
  /etc/letsencrypt/live/example.com/fullchain.pem (success)
  /etc/letsencrypt/live/img.example.com/fullchain.pem (success)

The following certs could not be renewed:
  /etc/letsencrypt/live/example.com-0001/fullchain.pem (failure)
  /etc/letsencrypt/live/example.com/fullchain.pem (failure)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
2 renew failure(s), 0 parse failure(s)

    Note: You have to wait after 10 mins and try to reload your domain on the browser and you can see SSL fixed.

    For cerbot SSL, you can follow the syntax below:

    certbot --force-renewal -d domain-name-1-here,domain-name-2-here

    For example:

    certbot --force-renewal -d www.quizdeveloper.com,quizdeveloper.com

    I hope it helpful for you.
