I had bought a domain in namecheap, and want to setting up my subdomain in digital ocean. Currently I only had one droplet and running ubuntu linux 14.04. My site was running in grunt at null:3000 which is localhost:3000. In apache2 conf, I had used proxypass redirect to my site. Right now, things are getting weird, my domain.com works yesterday, but today doesn't work anymore.

NameCheap

  • NS Record to digital ocean ns1, ns2 and ns3
  • A Record mydomain.com ipaddressdroplet
  • A Record subdomain.mydomain.com ipaddressdroplet

Digital Ocean

  • A Record mydomain.com ipaddressdroplet
  • A Record subdomain.mydomain.com ipaddressdroplet
  • NS Record to digital ocean ns1, ns2 and ns3 Apache2 Configuration

000-default.conf

<VirtualHost *:80>

        ServerAdmin webmaster@localhost
        ServerName www.mydomain.com
        DocumentRoot /var/www/mydomain

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

subdomain.mydomain.com.conf

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/subdomain
        ServerName subdomain.mydomain.com

        <Directory /var/www/subdomain>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride all
        Order allow,deny
        allow from all
                Require all granted
    </Directory>


        <Location />
                ProxyPass http://localhost:3000/
                ProxyPassReverse http://localhost:3000/
        </Location>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

/etc/apache2/sites-available/000-default.conf used for mydomain.com /etc/apache2/sites-available/subdomain.mydomain.com.conf for subdomain. I had used a2ensite command to activate my subdomain, but the site doesn't work, it show the site can't be reached. Currently, both sites doesn't work.

Hi @catergogo

If you have setup your domain to use DigitalOcean's name servers via your registrar (which in your case is NameCheap), then you only need to configure DNS records via DigitalOcean.
But note that changing name servers can take up to 48 hours, so your domain might be going in-and-out if the DNS records are not the same at both the old and new NS.

It would help a lot more if you posted your domain, but otherwise you can check the current name servers, A/CNAME/etc records with this command:

dig yourdomain.com NS
dig yourdomain.com A
dig www.yourdomain.com CNAME

Your Apache configuration looks correct, so this it probably just a domain issue.
Just to make sure of that, run sudo apachectl configtest.
