Problems while creating a certificate


#1

Hi there, I am trying to create a SSL certificate for a subdomain name but I am getting some errors. Any help please !!

I ran this command,
certbot certonly -a webroot --webroot-path=/var/www/{{ letsencrypt_domain_name }} -d {{ letsencrypt_domain_name }} -n --agree-tos --email {{ letsencrypt_email }}

My operating system is :
Debian 8 (Jessie)

My web server is:
nginx

My hosting provider:
Company servers

I can login to a root shell on my machine:
Yes

I’m using a control panel to manage my site:
No

Running this command produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org
An unexpected error occurred:
ConnectionError: HTTPSConnectionPool(host=‘acme-v01.api.letsencrypt.org’, port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError(’<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f7119e9c290>: Failed to establish a new connection: [Errno -2] Name or service not known’,))
Please see the logfiles in /var/log/letsencrypt for more details.

Looks like your server can’t connect to acme-v01.api.letsencrypt.org through HTTPS.

You might want to try to surf to https://acme-v01.api.letsencrypt.org/directory with a browser to see if that works or not.

Perhaps it’s a company firewall issue?

By the way, acme-v01.api.letsencrypt.org is offloaded through Akamai CDN services, not directly to Let’s Encrypt.
