Question

Another DNS Not Resolving Issue

Posted on June 15, 2020
DNS LAMP Stack Ubuntu
Asked by ScoutDigital

Hi DO Community, I’ve got a droplet setup at 67.205.185.20 and my dns for clients.nevilleco.com is setup and forwarding to this IP. I can ping the subdomain and get the IP address and DNSchecker.org does return the IP as well, but I’m getting a ‘site can’t be reached’ error trying to hit clients.nevilleco.com from the browser.

I believe the information above shows that DNS has propagated (although I only made this change this morning) and I want to get started on finding why it’s not resolving. My apache configuration is below

Hi there @ScoutDigital,

It looks like that your DNS is configured correctly and your webserver is also up and running, I’ve tested this with the following curl command:

curl -IL clients.nevilleco.com

The output bellow shows that the domain is resolving and that Apache is listening on port 80:

HTTP/1.1 301 Moved Permanently
Date: Tue, 16 Jun 2020 15:15:38 GMT
Server: Apache/2.4.29 (Ubuntu)
Location: https://clients.nevilleco.com/
Content-Type: text/html; charset=iso-8859-1

curl: (7) Failed to connect to clients.nevilleco.com port 443: Connection refused

However, you have an http to https redirect and it looks like that you do not have an SSL certificate installed so Apache is not listening on port 443, and this is why you are seeing the Connection refused error.

To fix that you can follow the steps here on how to issue a Let’s Encrypt SSL certificate for your domain name using certbot:

https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04

Hope that this helps! Regards, Bobby
