Nginx emerg unknown directive Brotli | Fixed

Have you been running into the following error message?

nginx: [emerg] unknown directive ‘brotli’

Well, fear no more. Our experts have your back. This error lets us know that Nginx has run into trouble with a configuration directive related to Brotli compression that it doesn’t recognize. In other words, it lets us know that this Nginx version does not support the brotli directive or module.

Here are some solutions for this error:

• Since older Nginx versions do not support Brotli compression, upgrade to a newer version that offers built-in support for Brotli. Brotli support was introduced in Nginx version 1.11.5.
• For those compiling Nginx from source, verify that Brotli support was included during the compilation process. This involves adding the –with-http_brotli_module option when executing the ./configure script before compiling Nginx.
• Additionally, double-check the Nginx configuration file for typos or misconfigurations related to Brotli compression. Also, verify the correct directive names are used in the configuration file.
• If we are using dynamic modules in Nginx, make sure the Brotli module is loaded correctly. Newer versions of Nginx support dynamic module loading.
• If the error with Brotli compression is causing an issue, GZIP compression is another option.
