DO - Unable to renew LetsEncrypt
I am trying to renew my SSL certificate (which has expired last week) using Certbot
raise ConnectionError(e, request=request) ConnectionError: HTTPSConnectionPool(host='acme-v01.api.letsencrypt.org', port443): > Max retries exceeded with url: /directory (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection > object at 0x7f55200944d0>: Failed to establish a new connection: [Errno -3] Temporary > failure in name resolution',))
Also, if I do ping 22.214.171.124, it works. However, ping google.com, nothing comes up.
ping acme-v01.api.letsencrypt.org does not work. But ping 126.96.36.199 (this IP is returned for acme-v01 from another system), and it responds.
I checked iptables -L
Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
How/ what else do I need to check what is stopping my DO droplet from renewal?
