How to to fix nginx loops between www and non-www versions ?

Question

Need to resolve this asap, this is basic setup but does not work, please have a look at config files below. site is looping between www and non-www until firefox of chrome stops it:

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

here is my nginx.conf

user xxxxxxx; worker_processes 1; pid /run/nginx.pid; include /etc/nginx/modules-enabled/*.conf;

events { worker_connections 1024; multi_accept on; }

http {

##

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 15;

server_tokens off;
client_max_body_size 16m;

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

include /etc/nginx/mime.types;
default_type application/octet-stream;

##

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

include /etc/nginx/sites-enabled/*;

server { listen 80 default_server; listen [::]:80 default_server; server_name _; return 444; }

}

and sites-available -

server { listen 80; listen [::]:80;

server_name  decor4all.com www.decor4all.com;

access_log /home/xxxx/decor4all.com/logs/access.log;
error_log /home/xxxxx/decor4all.com/logs/error.log;

root /home/xxxxx/decor4all.com/public/;
index index.php;

location / { try_files $uri $uri/ /index.php$is_args$args;

try_files $uri $uri/ /index.php?$args;

location ~ .php$ { try_files $uri =404; fastcgi_split_path_info ^(.+.php)(/.+)$; fastcgi_pass unix:/run/php/php7.1-fpm.sock; fastcgi_index index.php; include fastcgi_params; }

}

Heya,

If your website is stuck in a redirect loop between the www and non-www versions, it’s usually because your server configuration is telling it to redirect from www to non-www and vice versa. This is a common problem, and can often be resolved by carefully examining your server block configurations.

The part of your configuration that is responsible for the redirect loop might not be included in your main nginx.conf file. The redirect rules are typically located in the server blocks for the specific sites, which are included in the ‘sites-enabled’ directory.

Let’s assume that you want to redirect all www requests to the non-www version of your site. Your server block might look like this:

server {
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name example.com;

    location / {
        # Your site configuration
    }

    # Other configuration...
}

Here, the first server block matches requests to www.example.com and redirects them (with a 301 - Permanent Redirect) to example.com. The second server block is the one that actually handles requests to example.com.

Remember to replace ‘example.com’ with your own domain name.

After making changes, don’t forget to test your configuration with sudo nginx -t and if everything is okay, reload your Nginx configuration with sudo service nginx reload or sudo systemctl reload nginx, depending on your system.
