[Ibrahim]

I have produced successfull ssl for the domain: pakalot.com
Now i trying to produce another ssl for a second domain in the same server: negevejobs.co,il
But unfortunately, i encountered an error.

Please fill out the fields below so we can help you better.

My domain is: negevjobs.co.il

I ran this command: certbot-auto --apache -d negevjobs.co.il -d www.negevjobs.co.il

It produced this output:

• The following errors were reported by the server:

  Domain: negevjobs.co.il
  Type: connection
  Detail: Failed to connect to 78.47.95.100:443 for tls-sni-01

  To fix these errors, please make sure that your domain name was
  entered correctly and the DNS A 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 operating system is (include version): Debian Jessie

My web server is (include version): Apache2

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):

Hi @Ibrahim,

Are you sure that you don’t have any kind of firewall that might block inbound connections to this server on port 443?
