Dieser Server empfing keine rechtzeitige Antwort von einem vorgeschalteten Server, auf den er zugriff, um Ihre HTTP-Anforderung zu verarbeiten. Dies bedeutet normalerweise, dass der 504 gateway timeout nginx vorgeschaltete Server ausgefallen ist (keine Antwort zum Gateway/Proxy), eher als dass vorgeschalteter 504 gateway timeout apache Server und Gateway/Proxy sich nicht über das Protokoll zum Datenaustausch einig sind. Beheben von 504-Fehlern - allgemein Dieses Problem 504 gateway timeout aws rührt ausschließlich von einer langsamen IP-Kommunikation zwischen Computern auf der Website her, möglicherweise einschließlich des Webservers.

Beheben von 504-Fehlern - CheckUpDown Der Einsatz von Proxies und Caching nimmt im Web zu. Unser CheckUpDown-Roboter versucht immer sich zu dem realen Computer, der tatsächlich die Website hostet, 'durchzubohren', aber wir haben keine vollständige Kontrolle darüber, wo unsere HTTP-Anforderung tatsächlich landet.

Dies ist aber kein leicht zu behebender Fehler, da Ebbe und Flut des Internetverkehrs diesen Fehlertyp sehr schwankend machen. 504-Fehler im HTTP-Ablauf Jeder Client (z.B. Ihr Webbrowser oder unser CheckUpDown-Roboter) durchläuft den folgenden Ablauf, wenn er mit dem Webserver kommuniziert: Eine IP-Adresse aus dem IP-Namen der Site zuweisen (die URL der Site ohne das vorangestellte 'http://'). Dieses Nachschlagen (Umwandlung des IP-Namens in die IP-Adresse) wird durch Domain-Namen-Server (DNS) geleistet. Öffnen einer IP-Socket-Verbindung zu dieser IP-Adresse. Schreiben eines HTTP-Datenstroms über diesen Socket. Rückempfangen eines HTTP-Datenstroms vom Webserver als Antwort. Dieser Datenstrom enthält Statuscodes, deren Werte durch das HTTP-Protokoll bestimmt werden. Parsen dieses Datenstroms auf Statuscodes und andere nützliche Informationen.

no required headers for this class of status code. Since HTTP/1.0 did not 504 gateway timeout wordpress define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. http 504 nginx A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx http://www.checkupdown.com/status/E504.html status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx Th

It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The https://www.keycdn.com/support/504-gateway-timeout/ first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard 504 gateway wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear 504 gateway timeout in the response payload and in documentation; not in the place of an actual HTTP status code).

A 504 Gateway Timeout indicates that the proxy / edge server did not get a response from the upstream / origin server in a given time window.

If you are not the website owner of a page which is returning a 504 Gateway Timeout error, it usually isn't your problem to fix. Most of the time it must be dealt with by the people who set up the network at the site that hosts the web server. That being said, the following are two possible reasons for a
