I was trying to set up a sub domain when suddenly I can no longer connect to my primary domain. I have a server set up with nginx. I am still learning this whole process and would really appreciate some help in what to do to fix this. Let me know what files I should include that would help you to help me fix this issue.

Hello,
In addition to what has already been mentioned, I would recommend following these steps in case that you are having any problems with your nginx server and you are unsure on what the problem is:
systemctl status nginx
If nginx is running you should see something like this:
● nginx.service - The nginx HTTP Server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2019-11-19 09:37:46 UTC; 2 days ago
Docs: https://httpd.nginx.org/docs/2.4/
If nginx is not running then the output would look like this:
● nginx.service - The nginx HTTP Server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
Active: inactive (dead) since Fri 2019-11-22 08:41:01 UTC; 39s ago
Docs: https://httpd.nginx.org/docs/2.4/
systemctl start nginx
Then check the status agian and make sure that nginx remains running.
systemctl enable nginx
nginx -t
If you get an error, you would need to fix that problem and then you could restart nginx:
systemctl restart nginx
Syntax OK
when running nginx -t
then your confiruation is correct, so I would recommend checking your error logs:tail -f /var/log/nginx/error.log
Find the user that your nginx service is running as:
ps auxf | grep nginx
If you are using Ubuntu, the user should be www-data
, so you would need to make sure that your files and folders are owned by that user, so nginx could read and write to those files:
chown -R www-data:www-data /var/www/yourdomain.com
netstat -plant | grep '80\|443'
ufw
allows TCP connections on port 80 and 443:ufw status
If this is the case, you can follow the steps from this article here on how to configure your ufw
:
https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-ubuntu-18-04
That is pretty much it, with all of the above information you should be able to narrow down the problem.
For more information I would suggest checking out this article here:
And here is also a quick video demo on how to do that as well:

I don’t really have a back end. The server is being run with nginx and I am coding the website myself. I am not using wordpress or any other kind of external program I am trying to build this all on my own.
/etc/nginx/sites-available/defaut
First to help make the configuration less confusing we can change the default file to whats desplayed below.
This returns a 444 on both ports 80 and 443 with a no respnse and closes the connection. This happens for any traffic hitting the server that is not
jchud.ninja
- essentially a black hole.From what I can see the issue is you have incomplete server blocks. As I do not know what you file name is I am just going to assume it is the following…
/etc/nginx/sites-available/jchud.ninja
and we will work with the blog.* domain.we first change
server_name _ blog.jchud.ninja;
to
server_name blog.jchud.ninja;
we romove…
root /var/www/blog.jchud.ninja/html;
index index.php index.html index.htm index.nginx-debian.html;
These directive are conflicting with what I am assuming is the desired destination. The server block should look like this now. \
Note that the blog application present on port 8080 needs to be active - Also noted these settings are non-ssl configurations.
The biggest issue that I see is that your server blocks are incomplete and in some cases conflicting. A couple questions I have are what are your back ends - ie your website (wordpress?) and your blog(ghost?)?

That is my default website nginx config, and this next one is my subdomains.
Can you post your NGINX Config for your domain and sub-domain?
