A 444 status code is thrown when a website unexpectedly closes the connection without sending any response to the client. It is an unofficial code and specific to NGINX. There are multiple reasons why NGINX might throw this error. It might occur when the server has identified your requests to be automated. The best way to avoid it is to make every effort to conceal your automated requests and make them resemble a regular user's browsing pattern. You can use undetected-chromedriver and pair it up with proxies from a reliable proxy provider like ScrapingBee. Or better yet, use ScrapingBee's web scraping API and let us handle the task of not getting blocked.
