HTTPS not working when putting ssl certificate with nginx in docker - docker

Question

I want to pass my server in HTTPS with docker nginx image, but it doesn't work, I have create a SSL certificate with openSSL like this on my server:
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt
and I well put the ip adress of my server by answering the questions.
On my server I have a docker-compose.yml which create the nginx container, my docker-compose.yml is like follow:
version: "3"
services:
nginx:
image: nginx:latest
container_name: nginx
depends_on:
- postgres
- monapp
volumes:
- /home/deployer/util/config/nginx-conf/nginx.conf:/etc/nginx/conf.d/default.conf
- /etc/ssl/certs:/etc/ssl/certs
- /etc/ssl/private:/etc/ssl/private
network_mode: host
# ports:
# - 80:80
# - 443:443
........
volumes with certificates are well passed to my container (I verified by navigating in the container with docker exec -it nginx bash) and IP adress of my container is the same as my server IP because there is network_mode: host.
My nginx configuration file nginx.conf is :
#-------- To redirect to ssl -------
#server {
# listen 80;
# listen [::]:80;
# server_name 159.65.124.219;
# location / {
# proxy_pass http://159.65.124.219:3000;
# }
#}
server {
listen 443 ssl;
server_name 159.65.124.219;
ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;
location / {
proxy_pass http://159.65.124.219:3001/;
error_log /var/log/front_end_errors.log;
}
}
So I just want that when I go to https://159.65.124.219:443/ it brings me to http://159.65.124.219:3001/ but this is unfortunately not working and I don't know why.... I have search on a lot of forum since more than 1 week.... please help.... Thanks by advance
