Multiple Wordpress sites on single droplet with NGINX - problem with Server Block

I have two Wordpress sites installed, example.com and test.com. Server is Nginx. I configured my local /etc/hosts so that example.com, www.example.com, test.com and www.test.com - all point to the ip address of my VPS. It works, but only partially. The URL http://test.com works as expected, and I see the correct Wordpress site. However, http://example.com sends me to the page directed by the default Server Block, and that’s not what I want.

Thank you for taking the time to read my question and working to help me.

For the reference, here are the 3 Server Blocks I have: default, example.com and test.com.

# default

	listen 80 default_server;
	listen [::]:80 default_server;

	root /var/www/html;

	}
}
