Кокпит через NGINX — настройки делают другие сервисы недоступными

Чего здесь не хватает?

Проблема возникает не на всех устройствах. Некоторые показывают, что «Это соединение небезопасно». для редмайна и gitlab. Но кабины нет. Решение загадки теперь заключается в том, что правила для Gitlab и Redmine не являются полными, и запросы https застревают в никуда.

Правила для порта 443 (https) отсутствуют. Теперь я поменял блоки на два:

1. Перенаправить http-запрос на https
2. прослушивать https-запросы и пересылать их приложению

Теперь это выглядит так:

/etc/nginx/sites-available/gitlab.<myserver> связан с /etc/nginx/sites-enabled/gitlab.<myserver>

      # redirect http request to https while keeping the request uri
server {

    listen 80;
    listen [::]:80;

    server_name gitlab.<myserver>;

    return 301 https://gitlab.<myserver>$request_uri;
}

# https requests will forwarded to the server application
server {

    listen 443 ssl;
    listen [::]:443 ssl;

    server_name gitlab.<myserver>;

    location / {
        proxy_pass         http://<docker-net-ip>:<port>;

        # Note: You should disable gzip for SSL traffic.
