I am hosting a jekyll webpage example.com on on debian VM. I have successfully redirected all trafic on both 80 and 443 ports to localhost:4000 where the jekyll server is running.

I am trying to configure a Bitwarden that will be accessible on bitwarden.example.com. I have already installed it, using docker and docker-compose. I set up nginx configuration but when I try to access my bitwarden.example.com I get an “Welcome to nginx!” page.

Where should I redirect any incoming traffic on bitwarden.example.com, so that the service is accessible?

Finally, these are my files:

/etc/nginx/sites-available/example.com

server {
    server_name example.com www.example.com;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com-0003/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com-0003/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    root /home/azureuser/www-example/_site;
    index index.html;

    # First location block for proxying
    location /proxy {
        proxy_pass http://localhost:4000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    # Second location block for handling static files and pretty URLs
    location / {
        try_files $uri $uri/ $uri.html /404;  # This ensures that pretty URLs are handled correctly
        error_page 404 /404;
    }
}
server {
    if ($host = www.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    server_name example.com www.example.com;
    return 404; # managed by Certbot
}

/etc/nginx/sites-available/bitwarden.example.com

server {
   server_name bitwarden.example.com;


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/bitwarden.example.com-0001/fullchain.pem; # managed by Certbot

        location /proxy {

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
server {
    if ($host = bitwarden.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


   listen 80;
   server_name bitwarden.example.com;
    return 404; # managed by Certbot

}
