DigitalOcean is not redirecting website address to the droplet

After finishing setting up the droplet and website code, I tried to access the website, but all browsers returned 404. I double checked everything to see possible mistakes I made, but everything looks ok.

Entering the droplet IP on the browser returns the nginx default page, meaning that the droplet itself is fine.

Then I concluded that the problem resides in the address redirection process, I’ve deleted the A and AAAA configs and created them again. Still nothing.

DigitalOcean apparently can’t redirect the url request to my droplet.

From what I’ve seen from other questions, some people are having problems related aswell.

    I have a very similar issue with my droplet (Debian 9, Apache, MariaDB, PHP)

    americanpharoah.ca/john.php returns file not found
    167.99.190.8/john.php serves the info.php webpage (please note, I renamed the info file with my name to make sure I was looking at the correct folder)
    I suspect I am missing something in my config file for the virtual host

    <VirtualHost *:80>
    ServerAdmin admin@americanpharoah.ca
    ServerName americanpharoah.ca
    ServerAlias www.americanpharoah.ca
    <Directory /var/www/americanpharoah.ca/html/racehorses/public>
      Options All
      Require all granted
      Options Indexes FollowSymLinks Includes execCGI
      AllowOverride All
      Order Allow,Deny
      Allow From All
    </Directory>
    DocumentRoot /var/www/americanpharoah.ca/html/racehorses/public
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =americanpharoah.ca [OR]
RewriteCond %{SERVER_NAME} =www.americanpharoah.ca
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

    after checking the CertBot and a few other things, my colleague took a look and we discovered that I had left my previous IP address pointing to the Cloudways IP address I used during a trial.
    just had to comment that line out of the hosts file (C:\Windows\System32\drivers\etc\hosts) on my laptop !

Hello,

Everything seems to be working just fine but you are redirecting your http traffic to https and it looks like that you have not configured Nginx to listen on port 443. You need to install an SSL certificate, sort out your server block for port 443 and the site will start loading as normal.

You can see the redirect simply by running this curl command

curl -IL advicequest.com

The output that you would get would be something like this:

HTTP/1.1 301 Moved Permanently
Server: nginx/1.14.0 (Ubuntu)
Date: Fri, 12 Jul 2019 04:22:45 GMT
Content-Type: text/html
Connection: keep-alive
Location: https://advicequest.com/

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

Hope that this helps!
Bobby

    But certbot can’t generate an SSL certificate because the http-01 challenge fails.

    Do I need to hard-code the SSL settings into my website nginx config file?

    My output doesn’t return the error (7).

    curl -IL advicequest.com

HTTP/1.1 200 OK
Server: nginx/1.14.0 (Ubuntu)

    The output of “ufw status”: 

    Status: active

Nginx Full (v6)            ALLOW       Anywhere (v6)

    Chrome now is returning the nginx default page when trying the website address. Firefox still returns the “can’t connect page”. I’m so confused.

    /var/log/nginx/error.log: 
     2019/07/12 20:00:38 [notice] 6140#6140: signal process started

I destroyed the droplet and rebuilt everything, setting nginx first and then the website code. It works now.
