How to migrate gitlab from haproxy to Nginx?

Question

Nginx

we want to transfer gitlab from haproxy to Nginx, for some reason the config does not work
Nginx config

server
{
        listen 80;
        server_name gitlab.*.ru;

location /
        {
                return 301 https://gitlab.*.ru;
        }
}
server
{
        listen 443 ssl;
        server_name gitlab.*.ru;


        location /
                {
                        proxy_pass http://10.*.*.50;
                        proxy_set_header X-Forwarded-Proto https;
                        proxy_set_header X-Forwarded-Ssl  on;

                }

}

Through haproxy it works like this

global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon
    tune.ssl.default-dh-param 2048
    
    stats socket /var/lib/haproxy/stats

defaults
    mode                    http
    log                     global
    option                  httplog
    option                  dontlognull
    option http-server-close
    option forwardfor       except 127.0.0.0/8
    option                  redispatch
    retries                 3
    timeout http-request    10s
    timeout queue           1m
    timeout connect         10s
    timeout client          1m
    timeout server          1m
    timeout http-keep-alive 10s
    timeout check           10s
    maxconn                 3000


frontend www-http
bind *:80
reqadd X-Forwarded-Proto:\ http

frontend gitlab_front
bind 80.*.*.*:443
mode tcp
use_backend gitlab


backend gitlab
mode tcp
option ssl-hello-chk
server gitlab_server 10.*.*.*:443

in gitlab.rb
nginx['enable'] = true
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/git-le.crt"
nginx['ssl_certificate_key'] = "/ etc/gitlab/ssl/git-le-key.key"
nginx['proxy_set_headers'] = {"X-Forwarded-Proto" => "https",
"X-Forwarded-Ssl" => "on",}

Actually the question is why does not work through the Nginx config?

Answer 1

Where are the SSL settings in the lower config block? Plus, if you have encryption on an external nginx, adding it inside is pretty pointless.
