I'm starting with Nginx.

I installed on my server:

• 1 Drupal site on www.domaine.com


• 1 GoAccess site on analytics.omaine.com


• 1 Netdata site on monitoring.domaine.com

The IP address and domain.com must redirect to www.domain.com

All domain and subdomain dovent redirect to https

On my OVH web host, I created domains domain.com www.domain.com analytics.domain.com monitoring.domain.com pointing to the IP address of my server.

When I enter the IP address of my server in the browser's address bar, it redirects to analytics.domaine.com why ?

How to redirect to www.domain.com ?

Before creating the configuration for analytics.domain.com and monitoring.domain.com it worked.

When I test my configuration :

sudo nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

sudo nano /etc/nginx/sites-available/www-domaine-com
