What is causing this issue and how to resolve it. Reason: Access-Control-allow-Origin missing in cors header" when it's visible in the console. In this section, we’ll provide two different configuration examples for enabling CORS on an Nginx server. I'm getting a " Cross-origin request blocked. Nginx is a popular web server that can be easily configured to support CORS. This ensures that applications can access data and services hosted on various domains securely while maintaining the integrity of the user’s data. Open NGINX Server Configuration Open terminal and run the following command to open NGINX server configuration file. addheader Access-Control-Allow-Origin ' Access-Control-Allow-Methods The browser can initiate one or more HTTP methods to access the resources. In order to allow CORS in NGINX, you need to add addheader Access-Control-Allow-Origin directive in server block of your NGINX server configuration, or virtual host file. you can fix this on you'r local machine using a plugin/extension called Allow-Control-Allow-Origin and add you'r localhost into it. CORS ImportanceĬORS is essential for modern web applications, as it enables communication between servers and clients from different domains. Here is an example to allow origin Add the following in the server block of nf or in-use configuration file. This happens if you haven't set up CORS configuration correctly. If you have access to the server you can change your implementation to echo back an origin in the Access-Control-Allow-Origin header. We’ll also delve into key CORS concepts, such as allow-origin, allow-methods, allow-headers, and expose-headers. More than one Access-Control-Allow-Origin header was sent by the server. In this blog post, we’ll explore the importance of CORS, how it works, and how to configure it in Nginx for different scenarios.

By providing a way for web applications to request resources from different domains, CORS helps overcome the limitations of the Same-Origin Policy (SOP), which restricts web applications from accessing data on a different domain than the one serving the application. Cross-Origin Resource Sharing (CORS) is a crucial mechanism for enabling secure communication between web servers and browsers.
