How to get certbox --nginx working?

Help
1

Hi everyone,

I have a certbot certificate successfully working for two domains and a blog which is a subdomain of one of the domains.

I am trying to add another subdomain to the certificate but even after successfully renewing and adding the domain to the certificate it still does not visit as a protected url.

Here is the results of my certbot certificates command:
Note: all domains with example are currently working. newdomain is working as well, but the subdomain blog.newdomain.io is what is not working and I am trying to add.

  Certificate Name: blog.example.net
    Domains: blog.example.net www.blog.example.net
    Expiry Date: 2018-02-28 01:21:48+00:00 (VALID: 72 days)
    Certificate Path: /etc/letsencrypt/live/blog.example.net/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/blog.example.net/privkey.pem

  Certificate Name: blog.newdomain.io
    Domains: blog.newdomain.io www.blog.newdomain.io
    Expiry Date: 2018-01-20 01:28:08+00:00 (VALID: 33 days)
    Certificate Path: /etc/letsencrypt/live/blog.newdomain.io/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/blog.newdomain.io/privkey.pem

  Certificate Name: newdomain.io
    Domains: newdomain.io www.newdomain.io
    Expiry Date: 2018-02-28 01:21:59+00:00 (VALID: 72 days)
    Certificate Path: /etc/letsencrypt/live/newdomain.io/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/newdomain.io/privkey.pem

  Certificate Name: example.net
    Domains: newdomain.io blog.newdomain.io blog.example.net example.ca example.net www.blog.newdomain.io www.blog.example.net www.newdomain.io www.example.ca www.example.net
    Expiry Date: 2018-03-17 01:16:52+00:00 (VALID: 89 days)
    Certificate Path: /etc/letsencrypt/live/example.net/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/example.net/privkey.pem

I have tried running certbot --nginx but it is returning this error:

Error while running nginx -c /etc/nginx/nginx.conf -t.

nginx: [emerg] open() "/etc/nginx/snippets/ssl-blog.example.io.conf" failed (2: No such file or directory) in /etc/nginx/conf.d/blog.example.io.conf:31
nginx: configuration file /etc/nginx/nginx.conf test failed

The nginx plugin is not working; there may be problems with your existing configuration.
The error was: MisconfigurationError('Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] open() "/etc/nginx/snippets/ssl-blog.example.io.conf" failed (2: No such file or directory) in /etc/nginx/conf.d/blog.example.io.conf:31\nnginx: configuration file /etc/nginx/nginx.conf test failed\n',)

The redacted domain names make it a bit confusing, but the error message seems to suggest that your nginx configuration is referring to a file that doesn’t exist - perhaps one that’s been deleted? What’s on the mentioned line 31 of /etc/nginx/conf.d/blog.example.io.conf?

(Note that certbot --nginx might not work right now anyway, due to the ongoing tls-sni-01 issue, but it should be fixed in an upcoming certbot update, or you can use certbot -a webroot -i nginx if you can’t wait. However, while your config is broken it will likely have the same problem)
