将 HTTP 重定向到 NGINX 中的 HTTPS，闪亮的服务器不工作

Question

Here I am following this tutorial to set up a shiny server and redirect http to https via nginx.

I set my /etc/nginx/sites-available/example.com with the configurations below. I manage to access the shiny app myapp through https://example.com . This means nginx is correctly routing https://example.com to http://example.com:3838/myapp .

The problem is that when I visit http://example.com nginx does not redirect me to https://example.com as it should.

Any ideas why this it happening?

server {
   listen 80 default_server;
   listen [::]:80 default_server ipv6only=on;
   server_name example.com www.example.com;
   return 301 https://$server_name$request_uri;
}

server {
   listen 443 ssl;
   server_name example.com www.example.com;
   ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
   ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
   ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
   ssl_prefer_server_ciphers on;
   ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL;

   location / {
       proxy_pass http://my_server_ip:3838/myapp;
       proxy_redirect http://my_server_ip:3838/myapp/ https://$host/;
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection $connection_upgrade;
       proxy_read_timeout 20d;
   }
}

I think the error is here. On the one hand you should enter the address of the app, eg 127.0.0.1 and on the other hand you want to forward to the folder /myapp/. But this works different with Nginx.

Remove: /myapp from proxy_pass and proxy_redirect
