Need help about setup domain when deploy!!!

[KyoRion]

I pointed my domain to the server with A record when installing the sample with nginx of the server the domain is confirmed to be accepted to the server but when I add the domain to the environment files as instructed in the documentation I can not access the website. I followed the steps according to the installation instructions on localhost without transferring the domain everything works normally

I saw website just response "HTTP take to long to response".
