nginx mutiple domain with ssl and www redirection

nginx redirection is not working as expected with ssl and www redirection.

I have two domains say, domain1.com and domain2.com. I need to have https with www redirection on both ie https:/www.domain1.com. and https:/www.domain2.com.

but when i take www.domain2.com its redirected to https:/www.domain1.com.

Please see the configurations

domain1.com

server {
    listen       8080;

    server_name  domain1.com;
    return       301 https://www.domain1.com$request_uri;
}

server {
    listen 443 default_server;
    ssl on;
    ssl_certificate /root/ssl/dom1/unified.crt;
    ssl_certificate_key /root/ssl/dom1/my-private-decrypted.key;


    root /var/www/dom1.com/html;
    index index.php index.html index.htm;

    server_name  www.domain1.com;

    }

domain2.com

server {
    listen       8080;
    server_name  domain2.com;
    return       301 https://www.domain2.com$request_uri;
}

server {
    listen 443;
    ssl on;
    ssl_certificate /root/ssl/dom2/unified.crt;

    ssl_certificate_key /root/ssl/dom2/my-private-decrypted.key;

    root /var/www/dom2.com/html;
    index index.php index.html index.htm;

    server_name  www.domain2.com;

        }
