When your web browser (such as Chrome, Firefox, Brave, etc.) asks for site files and content whenever you open a web page. Through communication with the server, the browser communicates the user's preferred content, with the hope that the server will respond with the relevant data.

Here Are Some Causes of 406 Errors ;

Accept-ranges: 

 Security measures on some servers may limit the file size range in response. The 406 error message will be displayed if the response exceeds the acceptable range of bytes. 

Accept-encoding: 

This header section is designed to quickly send compressed files from the server to the browser. When certain HTML encoding formats are not accepted, a 406 error code is generated. 

Accept-language: 

 The "Accept-language" alias in "Accept-charset" highlights its focus on supporting languages from all over the world. 

Default MIME type: 

Sometimes, the browser might request a specific MIME ( Multipurpose Internet Mail Extensions) type from the server. MIME types include things like JPEG images, specific video formats, and basic text. If the server can't provide the requested MIME type, like with JPEG images, you may receive a 406 error. 

Accept-charset from request HTTP header: 

Character sets convert code into readable characters, but it's impossible to cover all languages and symbols globally. The ISO-8859 table is standard, and new character tables are released regularly to keep up with additions.
