Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I ran this command:
sudo certbot --nginx -d area51.mynetstuff.com
It produced this output:

Failed authorization procedure. area51.mynetstuff.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://area51.mynetstuff.com/.well-known/acme-challenge/ahazTqRH09E8hDatGMGff0LDt5orXd_2lJHDrQq5RQw: Error getting validation data
The following errors were reported by the server:
Error getting validation data
To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you’re using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
My web server is (include version):
The operating system my web server runs on is (include version):
Ubuntu 16.04 (I’m happy to run this on 18, but I thought that might be part of the problem)
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot):
/facedesk I’m out of ideas
Of note, I believe this is something I’m missing on my new ubuntu instance, as if I boot up my old one (with lots of extra services on it), it still renews just fine (when I checked 2mo ago). Any new instance I have set up (trying to clean up my containerization) I can’t get a cert to validate HALP!
I have tried and checked several of the things listed in the numerous other “Error Getting Validation Data” posts, with no luck.
I shall send you a beer/coffee of choice!
