Nginx and my public ip partially work

Hello evryone,
I run Nginx on a raspberry pi 3 with a wordpress site

When I launch my site with my public ip adresse (that I forwarded in my router to the raspberry local ip with port 80) is ok, the site is launched but...

css and others things are not loaded because the ip adress used is still the local adresse instead of the public one

For example, in the browser console I see

"http://192.168.1.2/wp-content/themes/radiate/style.css?ver=5.4.1"
But it should be "http://my-public-ip-adress/wp-content/themes/radiate/style.css?ver=5.4.1"
So the css file is not loaded

Here are my settings

wp-config:
define('WP_HOME','http://my-public-ip-adress');
define('WP_SITEURL','my-public-ip-adress');

of course, when I run the wordpress locally, everythings is fine
