Nginx is known for its high performance, low resource usage, and scalability. Additionally, it is a popular choice for reverse proxying, load balancing, and caching.

What is a Subdomain?

A subdomain is a section of a domain that can be used to organize your website’s content into different categories. For example, instead of having all your content under www.example.com, you can create subdomains such as blog.example.com or store.example.com.

What is a Server Name?

In the context of Nginx, a server name is a directive that tells Nginx which server block to choose when handling a request. It is usually set in the server block’s declaration and can be either a domain name or an IP address.

What is Nginx Subdomain Conflicting Server Name?

Nginx Subdomain Conflicting Server Name is an error message that occurs when you have two or more server blocks with the same server name but different subdomains. This conflict prevents Nginx from deciding which server block to choose when handling a request.
