I installed a LEMP server on an odroid c2 (LEMP=Nginx, mariadb, phpmyadmin, php-fpm et wordpress).
Eveything is woking in my home local network but i cannot access server from outside my local network.
To have access to the server from the www, having a classical internet box routed, I've assigned a fixed ip to the server (192.168.0.xx) and redirected port 80 for this ip in tcp.
I also took a free domain name for the public IP of my freebox.(IP xxx.xxx.xxx.xxx -> my-site.ocry.com).

This domain name is well registered and active in the parameters of my internet box provider (Reverse DNS custom).
When I test from the www url site (www.domain name or public IP port 80) it fails and I have a page: "This site is inaccessible, 127.0.0.1 took too long to answer".
it's been 4 days that I can not find a solution; thanks for any help;

I went to https://ping.eu/,
a DNS lookup on the domain name refers to the public IP of my BOX.
a PING is successful
a port check tells me that port 80 and 8080 are open.

here is my server config in /etc/sites-available/my-site


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

server_name my-site.ocry.com;
root /var/www/my-site;

index index.php index.html;

location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
fastcgi_read_timeout 600;
}
}

It sounds to me like one of these things fail

(1) The public IP address of your home network changes because of DSL/whatever reconnects, but this is not reflected in the A record of your DNS entry for the domain. => check dynamic DNS options to reflect changes in the home network public IP address in the DNS record.

(2) There is a problem with port forwarding from your NAT router to your local server. => check the port forwarding, e.g., from your mobile, and see if calling the web site address gets logged in your NGINX access.log

(3) Your local server is not aware of its public DNS name, so it will create URLs that refer to localhost (127.0.0.1). => Check the configuration of your host to handle this properly, or use the proxy_redirect directive to rewrite URLs to respect your public DNS name (https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_redirect).

Hello j94305,

(1) my Public IP adress is static for sure .
(2) port forwarding is absolutely ok (a port check tells me that port 80 and 8080 are open for my server ip).
(3) host is correctly configured

EDIT: SOLVED MY PROBLEM! :

In wordpress, edit wp-config and add:

define( 'WP_HOME', 'http://my-site.com' );
define( 'WP_SITEURL', 'http://my-site.com' );

SAVE


in phpmyadmin go to wp-options table and search in "option name" column for HOME URL et SITEURL.
Changed 127.0.0.1 to http://my-site.com for each and clik execute each time.

Made a:

curl -I http://my-site.com

gave a:

$[i] curl -I http://mon-site.ocry.com

You can see on last line LINK that there are 2 http://
So i made in server a:

sudo systemctl restart php7.2-fpm.service
sudo systemctl restart nginx.service
sudo systemctl restart mariadb.service

And in the phone i used (to connect externaly to the server) erases all navigator cache.

That all. Thank you. Does I need to mark this as solved in title?
