webserver - Not able to configure Caddy server to use TLS with my domain name

Question

I already have pointed domain's A/AAAA records point to my server's IP address and I do see Caddy home page when I put my server's IP address in the browser but not with domain name.

Not sure if my Caddyfile changes are even getting reloaded.

Hit in browser:

http://10.20.30.40 -- I see Caddy home page when I hit my machine's ip address
http://www.mytekworld.com -- The browser just keeps spinning when I hit the domain name
https://www.mytekworld.com -- The browser just keeps spinning when I hit the domain name

sudo nano /etc/caddy/Caddyfile

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace the line below with your
# domain name.
www.mytekworld.com

# Set this path to your site's directory.
root * /usr/share/caddy

# Enable the static file server.
file_server

# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080

# Or serve a PHP site through php-fpm:
# php_fastcgi localhost:9000

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

Answer 1

This appears to be a DNS issue.

Make sure your A record looks something like this

A 10.20.30.40

If your A record is formatted properly please update your question with the DNS record and your DNS provider (Cloudflare, Netlify, Godaddy, etc.)
