Nginx server blocks not redirecting

Question

I am working on a project at https://modernamedia.no/ and I am trying to do a multiple of things

• redirect all calls to www.modernamedia.no to https://modernamedia.no/
• proxypass localhost:5000 to api.modernamedia.no
• redirect all http calls to https.

the last one is working. however, the first two are not working. You can test it yourself by going to https://www.modernamedia.no/

I am also struggling reaching my localhost through an API call, but that may be a code related problem.

You should make sure Certbot does not touch your nginx configuration files. It uses a problematic and fragile approach to configure things.

Use the following approach instead:

# Redirect HTTP requests to HTTPS
server {
    listen 80;
    server_name modernamedia.no www.modernamedia.no;

    # Allow serving of Letsencrypt HTTP auth challenges

    location /.well-known {
        try_files $uri $uri/ =404;
    }

    # Do redirect to https
    location / {
        return 301 https://modernamedia.no$request_uri;
    }
}

# Redirect https://www.modernamedia.no to https://modernamedia.no
server {
    listen 443 ssl http2;
    server_name www.modernamedia.no;

    ssl_certificate /path/to/ssl_cert;
    ssl_certificate_key /path/to/ssl_key;

    return 301 https://modernamedia.no$request_uri;
}

# https://modernamedia.no
server {
    listen 443 ssl http2;
    server_name modernamedia.no;

    ssl_certificate /path/to/ssl_cert;
    ssl_certificate_key /path/to/ssl_key;

    # Actual web site configuration here
}
