Http not redirecting to https nginx - nginx

Question

I have set up letsEncrypt free ssl with certbot on ubuntu 14.04 from digitalocean tutorial.
If anyone tries to access the page on 80 ( http://gw2axiom.com ) , it shows 404 not found.
If you try https://gw2axiom.com it will work normally. After that, http will redirect to 443.
What could be the reason?
My nginx config file is the following :
# FORGE CONFIG (DOT NOT REMOVE!)
include forge-conf/gw2axiom.com/before/*;
server {
listen 443 ssl;
server_name gw2axiom.com www.gw2axiom.com;
root /home/forge/gw2axiom.com/public;
ssl_certificate /etc/letsencrypt/live/gw2axiom.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/gw2axiom.com/privkey.pem;

Answer 1

Put this before your current server entry:
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name gw2axiom.com;
return 301 https://$server_name$request_uri;
}
After that restart your nginx webserver and everything should work fine.
