I can't access my blog by IP address

Question

I tried install a Ghost CMS on a droplet, actually the installation looks like okay in terminal, but I can’t access my site to see it… I think the DNS is not propagated yet since It will complete 48hours today later. But I can’t access the blog using the ip address. Instead it returns to me “ERRCONNECTIONREFUSED”
What could I have done wrong?

Hey @arnsoares ,

There are a lot of possible reasons why this could be happening. I would start with the following:

Check the Nginx logs - tail -n 20 /var/log/nginx/error.log
Check my php version - php -v
Check my Nginx config and check if the PHP lines are accordingly set up to my version (php7.2-fpm.sock/php7.3-fpm.sock/e.t.c)
Check my Nginx config and make sure there are no other virtual blocks that are interfering with the one I’m trying to access.
Check if my permissions and ownership are properly set.
Ping my domain and make sure the IP I’m getting is the same as the one of the Droplet, I’m trying to set up.

I hope this helps and feel free to keep the conversation going!

Best regards,

Hi @denislavgavrilov, thank you!

Actually, I suspect that the problem was being caused by the Let’s Encrypt, not sure… but I followed this tutorial https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04 and it worked.

The thing is.. before I follow this tutorial I tried to reconfigure ngynx and mysql and as I am a noob. things got hard… so I destroyed the droplet, create a new one and had same problems with the new ip address… so then I tried solve the encryption.

Now the only thing I am weird is when I try to access my site by the IP it shows the error

This tutorial will show you how to set up a free TLS/SSL certificate from Let’s Encrypt on a Ubuntu 16.04 server running Apache as web server. TLS certificates are used within web servers to encrypt the traffic between server and client, providing extra security for users accessing your application.

  Hey @arnsoares ,
  
  The link you posted seems to be for Apache webserver, and not Nginx. If you are using Nginx, you should use this:
  https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04
  
  Also, when I access your domain I still get the 502 HTTP code from NginX. Are you sure you forwarded the domain to your new droplet?
  
  Best regards,

  Hey @denislavgavrilov!
  
  You’re right! I think I solve that.
  But I still can’t access my site using www just selvabim.com.br.
  
  I use CNAME to create an alias, but still not working… =/

  Hey @arnsoares,
  
  I’m glad this worked for you!
  
  I am having no problems accessing your website with www. Do you still have this problem on your end? If this is the case, maybe you edited the hosts file and forgot about it.

I tried a lot of things including destroying the droplet and creating another. I discovered that the problem was in the let’s encrypt configuration. So now, I think this is working and I am able to access the site.

But I am having another problem. I am having bad gateway when access my site using ‘www’ so. I can run this using just https://selvabim.com.br
But not when I try https://www.selvabim.com.br

I am using an A record to “selvabim.com.br” directing to the IP Address “68.183.125.93” and two CNAME’s “www.selvabim.com.br” and “www.selvabim.com.br.selvabim.com.br” with value of “selvabim.com.br”

I add in the nginx configuration
“sudo nano /etc/nginx/sites-available/default”
server_name www.selvabim.com.br selvabim.com.br;

In ghost config url I added the: https://selvabim.com.br
