Nginx redirect loop

I have Xenforo 2 running on Centminmod Nginx.

I have tried to edit the domain files to redirect to https://www.mydomain.com

Once I save the files and restart Nginx I get the redirect loop.

I just cant see what is wrong.

Code:
# Centmin Mod Getting Started Guide
# must read http://centminmod.com/getstarted.html
# For HTTP/2 SSL Setup
# read http://centminmod.com/nginx_configure_https_ssl_spdy.html

# redirect from www to non-www  forced SSL
# uncomment, save file and restart Nginx to enable
# if unsure use return 302 before using return 301
 server {
   server_name therailwaymen.com www.therailwaymen.com;
    return 301 https://mydomain.com$request_uri;
 }

FYI for Centmin Mod Nginx based issues might also ask on Centmin Mod community forums https://community.centminmod.com/forums/forum-software-usage.34/ ;) and for Centmin Mod http to https redirect documentation at https://centminmod.com/nginx_domain_dns_setup.html#httpsredirect

I would test in incognito or private web browser session first on your local PC that accesses the site so to ensure that HTTP to HTTPS redirect works well before change 302 temporarily redirect to 301 permanent redirect

assuming mydomain.com = therailwaymen.com

right ?

to redirect to www version change this part from
Code:
 server {
   server_name therailwaymen.com www.therailwaymen.com;
    return 301 https://mydomain.com$request_uri;
 }

server {
  listen 443 ssl http2;
  server_name mydomain.com www.mydomain.com;
to
Code:
 server {
   server_name therailwaymen.com www.therailwaymen.com;
    return 302 https://www.therailwaymen.com$request_uri;
 }

server {
  listen 443 ssl http2;
  server_name www.therailwaymen.com;
then restart nginx server after making the vhost changes
Code:
ngxrestart
