try to ping a public domain (e.g. google.com) from your droplet. If it failed, try to ping a well known IP address (e.g. 8.8.8.8) if it also failed, then you have connection issue. . But if ping an IP is success, then you have DNS issue. . from my previous experience, I face similar issue due to DNS resolution failed. When repair the DNS in my instance ( I change my server DNS to Google DNS), the problem is then fixed. . re-check and re-setup your DNS configuration from your droplet.

Hello,

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

traceroute acme-staging-v02.api.letsencrypt.org

And:

telnet acme-staging-v02.api.letsencrypt.org 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! Regards, Bobby
