I have a React app deployed on IP but not in custom domain

Hi all,

I have followed serveral tutorials on deploy a react app on Linode. I have a custom domain (.dev) registered with goDaddy that is currently redirected to Linode. That process went ok.

Rigth now I a have the issue that my IP adress proveed by the server in Linode actually renders the react app but my custom domain doesn't.

I have nginx and my /etc/ngninc/mydomain.dev file is this:

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

   server_name mydomain.dev;

   root /var/www/mydomain.dev;
   index index.html;

   location / {
      try_files $uri $uri/=404;

}
}

I have followed this tutorials and guide but anything works on custom domain. Is there any restrictions with domains of type .dev? or I've missed something.

tutorials and guides that I followed:
