DNS Problem: query timed out look up A for mydomain.com

I apologize in advance I’m completely new to working with Let’s encrypt and probably have missed some basics. I’m running:

./letsencrypt-auto certonly -a webroot --webroot-path=/usr/share/nginx/html -d mydomain.com

mydomain is of course my actual domain not mydomain, and I ran this actual domain through http://dnscheck.pingdom.com/ and it was all green / resolved and can be reached at it’s URL. The A records point to my digitalocean servers IP address. How do I troubleshoot this and proceed?

Same this here. Looks like we are not alone: DNS problem: query timed out looking up A?

Okay thanks for the post. maybe this is on their side it looks like? I was wondering if it had to do with the fact I’m using nginx as a proxy for multiple domains each with separate conf.d files, now I’m thinking that’s fine as long as each includes:

location ~ /.well-known {
    allow all;

I’m new to this and guessing in the dark a bit though. I’ll keep an eye on that thread, thanks again.

Yes, on their side. I would suggest to monitor the other thread.

Experienced the same issue today during a certificate renewal.
