Code-server.my_domain not directing to the code-server page

Hello!

I’m trying to setup code-server on CentOS 7, but I am unable to get to code-server.my_domain.

I am able to go to http://my_domain (which directs me to the CentOS welcome page), but going to code-server.my_domain or http://code-server.my_domain gives me the following message in Firefox:

"Hmm. We’re having trouble finding that site.

We can’t connect to the server at code-server.my_domain"

I’ve been following the instructions here, and I’ve gotten through step 2: https://www.digitalocean.com/community/tutorials/how-to-set-up-the-code-server-cloud-ide-platform-on-centos-7

I’ve copied and pasted the code into the /etc/nginx/conf.d/code-server.conf file, and it looks like this:

server { listen 80; listen [::]:80;

server_name code-server.my_domain;

location / {
    proxy_pass http://localhost:8080/;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection upgrade;
    proxy_set_header Accept-Encoding gzip;
}

}

Not sure what to do from here.

Looking forward to hearing back!
