Anyone can help why the renewal was failed :

Cert is due for renewal, auto-renewing…
Plugins selected: Authenticator apache, Installer apache
Attempting to renew cert ( from /etc/letsencrypt/renewal/ produced an unexpected error: HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError(’<urllib3.connection.VerifiedHTTPSConnection object at 0x7ff9cae9a518>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’,)). Skipping.
All renewal attempts failed. The following certs could not be renewed:

Thanks for anyone who try to help

What I could suggest is testing the connection to the letsencrypt api server. You could do that with these two commands:



telnet 443

Note that you need to run those two from your droplet.

Also if the connection is successful I would recommend trying to run the renewal manually.

Hope that this helps!
