524

Error 524 indicates that Cloudflare successfully connected to the origin web server, but the origin did not provide an HTTP response before the default 125 seconds Proxy Read Timeout. This can happen if the origin server is taking too long because it has too much work to do, for example, a large data query, or because the server is struggling for resources and cannot return any data in time. The error 524 occurs if the origin web server acknowledges (ACK) the resource request after the connection has been established, but does not send a timely response (within the Proxy Read Timeout delay, 125 seconds by default).
