How to solve if a renewal configuration file for yourdomain.com is invalid or missing

I have tried those steps on a Ubuntu 20.04 Server, with Openlitespeed

And the issue i was facing is that a commercial SSL was expiring and i wanted to replace it with a Let’sencrypt free SSL , but the installation of the Letsencrypt SSL was not successful as the old commercial ssl was not removed y any mean. so following the steps below solved the issue.

Step 1: Delete the Invalid Renewal Configuration

Remove the problematic renewal configuration file:

            
              sudo certbot certificates

Look for the entry for yourdomain.com and confirm its expiration date.

Step 2: Reissue the Certificate

If the existing certificate is valid but needs to be reissued (e.g., because of a misconfiguration), you can force Certbot to reissue it:

Use the --force-renewal flag:

            
              sudo certbot certonly --force-renewal --standalone -d yourdomain.com -d www.yourdomain.com

This will overwrite the existing certificate.

Step 3: Delete and Recreate the Certificate

If the existing certificate is invalid or causing issues, you can delete it and then request a new one.

Delete the existing certificate:

            
              sudo certbot delete --cert-name yourdomain.com

2. Request a new certificate:

            
              sudo certbot certonly --standalone -d yourdomain.com -d www.yourdomain.com

Step 4: Verify Port Availability

Certbot’s --standalone mode uses port 80 to validate your domain. Ensure that no other service (like LiteSpeed or Apache) is occupying port 80 during this process:

Stop LiteSpeed:

            
              sudo systemctl stop lsws

2. Run Certbot again to request the certificate:

            
              sudo certbot certonly --standalone -d yourdomain.com -d www.yourdomain.com

3. Restart LiteSpeed after obtaining the certificate:

            
              sudo systemctl start lsws

Step 5: Check Logs for Details

If the issue persists, inspect the log file for more specific errors:

            
              sudo cat /var/log/letsencrypt/letsencrypt.log

The log will provide additional context to troubleshoot the issue.

Step 6: Apply the Certificate in LiteSpeed

Once the certificate is successfully obtained, update your LiteSpeed virtual host configuration to point to the new certificate and private key files:
- Certificate: /etc/letsencrypt/live/yourdomain.com/fullchain.pem
- Key: /etc/letsencrypt/live/yourdomain.com/privkey.pem
Restart LiteSpeed to apply the changes:

            
              sudo systemctl restart lsws
