Why 403 Denied by Referer ACL (Access Denied)?

This is due to hotlink protection (reduce number of requests, thus saving server’s workload) by Tencent or Alibaba Cloud – basically it checks for a speific “Referer” value in the HTTP Request Header. It is not easily (or simply not possible) to modify the HTTP Referer when visiting a external static resources (video or images), however, there is a workaround to bypass this security check using server code (see this PHP: PHP Code to Redirect with 302 and a Referer).
