Nginx Nodejs File Upload 401 Unauthorized

What is Nginx Nodejs?

Nginx Nodejs is an open source web server designed to take advantage of the Apache web server’s strengths while taking a more lightweight approach to web serving and streamlined file upload process. It offers a variety of features, components, and settings that make it incredibly beneficial for any webmaster or developer tasked with data hosting, serving, uploading, and processing.

Nginx is an open-source, cross-platform web server and proxy designed to serve as a caching layer for the web and file transfer enabled over the Internet. It is based on an event-driven, non-blocking I/O model, and supports various operational modes, such as web serving, static file serving, reverse proxy, caching, and more. In addition, it is extremely fast and efficient, providing unparalleled performance when compared to other web servers, and is designed to be highly customizable for specific hosting needs.

Nodejs is a server-side JavaScript platform designed to allow developers to create web applications that are scalable, powerful, and highly efficient. It is built around an asynchronous, event-driven architecture, allowing developers to perform a variety of tasks, such as data fetching, processing, and rendering, concurrently and in a non-blocking manner. It is built upon the JavaScript V8 engine, providing a fast and reliable runtime environment, and is used in a wide variety of projects, from real-time video streaming to content management systems.

What is the Nodejs File Upload?

The Nodejs File Upload allows developers to securely and quickly upload files from the client’s computer to the server. This process involves several steps, such as validating the file type, setting the file size limit, and configuring the underlying connection from the client to the server. This allows developers to ensure that only the type of file requested is being transferred, and that all confidential information stored on the user’s computer is protected.

When using Nodejs File Upload, developers have several options that can be used to secure the process. For example, files can be encrypted in transit via HTTPS or FTP, ensuring that all confidential data is fully protected. Additionally, developers can limit the types of files accepted, as well as set an upper limit on the file size to prevent users from uploading excessively large files.

Nodejs File Upload is a great tool to help make sure the data upload process is secure and efficient. By using the built-in security features, developers can ensure that all confidential information stored on the user’s computer is kept safe, as well as help limit the types of files that can be uploaded, preventing any malicious file types from being uploaded to the server.

Why Do We Get Nginx Nodejs 401 Error?

Nginx Nodejs 401 errors happen when there are authentication issues with the web server or when invalid data is posted to a web server, resulting in authorization issues. The error code 401 is commonly seen when the web server’s authentication mechanism has been configured to reject the client’s request because it does not contain authentication credentials or authorization data, or when the data provided did not meet the criteria laid out in the authorization parameters.

In the case of a Nodejs file upload, the server will first check if the file being uploaded meets the criteria for the specified file type and size limit. If the file does not, the server generates a “401 Unauthorized” error code. This could happen due to incorrect file types being posted or due to an excessively large file size being posted.

In some cases, a “401 Unauthorized” error could be caused by a server security issue. The server might detect an unauthorized request for a file upload and respond with a “401 Unauthorized” error code. This is a safety measure to ensure that malicious requests do not succeed.

How to Solve Nginx Nodejs File Upload 401 Unauthorized?

The most common solution to this issue is to use Nginx’s built-in security features to limit which types of files are allowed to be uploaded and to ensure that the files uploaded fall within the specified size limit. To do so, the server administrator should check the configuration settings of the server and ensure the file type setting is set to “only accept” the types of files desired.

Additionally, the server administrator should also configure the server to only accept files that fall within the set size limit. To do this, the server administrator should configure the size limit to match the limit set on the client side, helping to prevent excessively large uploads. This should help prevent the “401 Unauthorized” error code from appearing.

In some cases, it may be necessary to use a third-party application to bypass the server’s security checks. This is not ideal, as it defeats the purpose of having strong security measures in place, but it is sometimes the only option. The application should be designed to check for valid file types or sizes, before allowing the file upload to proceed.

Does Nginx Nodejs File Upload Support HTTPS?

Yes, Nginx Nodejs File Upload supports HTTPS, improving the security of the file upload process. HTTPS is an acronym for Hypertext Transfer Protocol Secure (HTTPS). It is a protocol which allows encrypted communication between two or more computers, ensuring that all data sent between computers is kept secure and private.

HTTPS is enabled on Nginx Nodejs servers by default, so that all data transferred is encrypted and secure. This ensures that all confidential data stored on the user’s computer is kept safe during the file upload process, as the data is kept hidden from potential malicious third-parties.


Nginx Nodejs file upload can be an invaluable tool for any webmaster or developer tasked with hosting, serving, uploading, and processing data. By using the built-in security and limiting features, developers can ensure that only the desired and accepted file types are being uploaded and kept on the server, as well as ensure that all confidential information stored on the user’s computer is kept safe. Additionally, Nginx Nodejs file upload also supports HTTPS, providing an extra layer of security for the upload process.
