URI::InvalidComponentError (bad component(expected scheme component): : https):

First of all, this problem is a persistent, and I'm trying to solve it for a week with 0 progress.

I'm working on a Ruby on Rails website and using Devise and Omniouth-<social media> for authentication. It was running very smoothly.

However, after configuring a paid SSL certificate with Nginx, with almost every redirect I get the following in my app console:

    Cannot render console from <my laptop ip>! Allowed networks: 127.0.0.1, ::1, 127.0.0.0/127.255.255.255

This message doesn't prevent the website from loading. But when user logs out (I'm using Devise for username/password user authentication). the website throws in the browser the error I mentioned earlier:

    

URI::InvalidComponentError bad component(expected scheme component): : https Extracted source (around line #322): def check_scheme(v) if v && parser.regexp[:SCHEME] !~ v raise InvalidComponentError, # line 322 "bad component(expected scheme component): #{v}" end

and I get the console error message twice.

Here is a part of my Nginx configuration :

server {
    listen 443 ssl;
    server_name <server-name>;

    client_max_body_size 15M;
    ssl                  on;
    ssl_certificate      <.pem file path>;
    ssl_certificate_key  <.key file path>;
    ...
    root <"public" directory inside my app directory>;
    access_log <ssl.access.log path>;
    error_log  <ssl.error.log path>;

    include /etc/nginx/default.d/*.conf;

    location / {
        proxy_pass http://127.0.0.1:3000;

        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header X-Forwarded-Proto: $scheme;
 }

Note: I'm running in development environment so far.
