Python Connection Error


My domain is:

I ran this command: ./certbot-auto

It produced this output: An unexpected error occurred:
ConnectionError: HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: /subscribe/c
ertbot (Caused by NewConnectionError(’<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7fbcd9
1d3a90>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’,))
Please see the logfiles in /var/log/letsencrypt for more details.

My web server is (include version): Apache/2.4.18 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 16.04

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

I was trying to instal certbot using Certbot-Auto, but python produced this error. Can you help?
