Hi,
When I run this command, certbot renew --dry-run , I am getting this output.
Processing /etc/letsencrypt/renewal/freeost.com.conf
Simulating renewal of an existing certificate for freeost.com and www.freeost.com
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: freeost.com
Type: serverInternal
Detail: During secondary validation: Secondary validation RPC failed
Domain: www.freeost.com
Type: serverInternal
Detail: During secondary validation: Secondary validation RPC failed
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Failed to renew certificate freeost.com with error: Some challenges have failed.
How to fix it?
Digital Ocean is my host. They reported something related to this at, DigitalOcean Status - Let's Encrypt SSL Provisioning
Thanks for your help.
