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;
