A 403 status code refers to the Forbidden response status. It is thrown by the server when it recognizes the request as being valid but is not willing to fulfil it. It might be caused by a lack of proper headers in your request so make sure you are passing all the required CORS/JWT/Authentication headers that the server is expecting.
However, if the website is normally accessible and sending proper headers is still not making it work, your requests might be getting recognized by the server as being automated. In such a scenario, make sure you are using undetected-chromedriver or a similar tool 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. This should help solve the issue.
