redirect non www to www nginx reverse proxy

I use the nginx reverse proxy in front of the apache web servers.
The nginx configuration file

server {
    listen 80;
    server_name domain-name1.com www.domain-name1.com;

    location / {
        proxy_pass http://192.168.1.110;
        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 {
    listen 80;
    server_name domain-name2.com www.domain-name2.com;

    location / {
        proxy_pass http://192.168.1.111;
        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;
    }
}

When I open a web browser and type domain-name1.com (domain-name2.com) it works great.

When I open a web browser and type www.domain-name1.com (www.domain-name2.com) I see then "The webpage is not available".
I would like domain-name1.com to be redirected to www.domain-name1.com.
I edited the configuration file

server {
    listen 80;
    server_name domain-name1.com;
    return 301 $scheme://www.domain-name1.com$request_uri;
    
    location / {
        proxy_pass http://192.168.1.110;
        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;
    }
}

When I open a web browser and type domain-name1.com , it is redirected to www.domain-name1.com but I still see "The webpage is not available".
The domain name and cname for www are valid on dns server.
Thank you for everyone help

I've not seen this syntax in the nginx config file.

What happens when you repeat your test after changing the server_name record to:

    server_name www.domain-name1.com domain-name1.com;

you can see the configuration everywhere

 server_name example.org www.example.org;

http://nginx.org/en/docs/http/request_processing.html
first non www and then www

There are a few questions/things you should check/try.

- How are named de domains in the containers? With or without the www.?
- In your proxy_set_header you are instructing nginx to pass the FIRST name on your config regardless of the redirection.
- Try changing $host in your proxy_set_header to $http_host, which should contain the value of the Header sent by the browser request.

And this is just out of curiosity, why do you need the leading www.? I actually strip that part to all my domains.

Anyway, try / check those suggestions and let us know. It should not be too difficult to get it going as you need it.

I found the manul on nginx web. It work perfectly now.

server {
    listen 80;
    server_name domain-name1.com;
    return 301 http://www.domain-name1.com$request_uri;
}

server {
    listen 80;
    server_name www.domain-name1.com;

    location / {
        proxy_pass http://192.168.1.110;
        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 {
    listen 80;
    server_name domain-name2.com;
    return 301 http://www.domain-name2.com$request_uri;
}

server {
    listen 80;
    server_name www.domain-name2.com;

    location / {
        proxy_pass http://192.168.1.111;
        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;
    }
}

Is it The configuration correctly ?
