server. When a client computer sends an HTTP request (typically a web browser, but can be any software application that is capable of making an HTTP request), it will pass through the server in order to obtain access to the desired URL. The proxy or gateway subsequently receives a 502 error, or invalid response, from the server located “upstream” in the attempt to fulfill the client request. The 502 proxy error ssl majority of the time the error is thrown, the upstream server is functioning appropriately. The proxy or gateway and upstream servers just cannot agree on the appropriate protocol for exchanging the information requested in the original client HTTP request. In many of these cases, either the proxy or upstream server are not configured correctly or are running incompatible software. Why Does a 502 Proxy Error Get Thrown? During a typical web browsing session, the following is an example of the classic HTTP cycle when a client computer and web server are communicating: Client Computer: The IP address of the desired website will be obtained from the URL of the site from the DNS server. Client Computer: The computer obtains an IP socket connection to the desired IP address and then sends an HTTP data stream through the IP address. Web Server: HTTP data is sent back to the client computer in response to the original HTTP request. The HTTP response will include status codes and other useful information for the client computer. Client Computer: If there is an error in the client’s request or server’s ability to respond, there will be an HTTP error code of 502 included in the

HTTP provides an orderly way for your Web browser to communicate with Web servers -- the machine chatter that goes on behind the scenes of your Internet experience. As a part of HTTP, whenever your browser interacts with a server, such as when you attempt to load a Web page, the server https://www.techwalla.com/articles/how-to-fix-a-502-proxy-error responds with an Internet status code telling the browser how the interaction went. The most common one is code 200, a generic message meaning that everything went fine. These codes are always present, but your browser doesn't typically show them to you, unless something goes wrong. Code 404 is the best-known HTTP error code, indicating that the server couldn't find what your browser was looking for, but code 502 also shows up from time to time.Code 502: Bad GatewayHTTP error code 502 indicates a "bad gateway" or "bad proxy." When you visit a website, your browser doesn't necessarily communicate directly with the server that hosts the site. Often there are middleman Web servers along the way called "gateways" that route Web traffic between networks. If something goes wrong between the gateway server and another server upstream -- which could be either the destination server or another gateway server -- the status code that makes its way back to you is code 502.

Ihr Webbrowser oder unser CheckUpDown-Roboter) zu erfüllen. Dieser Server empfing eine ungültige Antwort von einem vorgeschalteten Server, auf den er zugriff, um die Anforderung zu erfüllen. Dies bedeutet normalerweise nicht, dass der vorgeschaltete Server ausgefallen ist (keine Antwort zum Gateway/Proxy), sondern, dass vorgeschalteter Server und Gateway/Proxy sich nicht über das Protokoll zum Datenaustausch einig sind. Da Internetprotokolle ziemlich eindeutig sind, beduetet dies oft, dass eine oder beide Rechner falsch oder unvollständig programmiert wurden. Beheben von 502-Fehlern - allgemein Dieses Problem rührt von einer schlechten IP-Kommunikation zwischen nachgestellten Computern her. Dies kann möglicherweise den Webserver an der Site, die Sie besuchen wollen, mit einschließen. Bevor Sie dieses Problem analysieren, sollten Sie Ihren Browsercache vollständig leeren. Wenn Sie im Web surfen und dieses Problem bei allen Websites, die Sie zu besuchen versuchen, sehen, dann hat entweder 1) Ihr ISP einen großen Geräteausfall/eine Überlast oder 2) es ist etwas falsch mit Ihrer internen Internetverbindung, z.B. funktioniert Ihre Firewall nicht richtig. Im ersten Fall kann Ihnen nur Ihr ISP helfen. Im zweiten Fall müssen Sie, was immer es ist, dass Sie davon abhält das Internet zu erreichen, korrigieren. Wenn Sie dieses Problem nur bei einigen der Websites die Sie zu besuchen versuchen erhalten, ist es wahrscheinlich ein Problem bei diesen Sites, d.h. eines ihrer Ausrüstungsteile ist ausgefallen/überlastet. Wenden Sie sich an die Betreiber dieser Sites. Beheben von 502-Fehlern - CheckUpDown Wir überwachen Ihre Site auf Fehler wie 502. Der Einsatz von Proxies und Caching nimmt im Web zu. Unser CheckUpDown-Roboter versucht immer sich zu dem realen Computer, der tatsächlich Ihre Website hostet, 'durchzubohren', aber wir haben keine vollständige Kontrolle darüber, wo unsere HTTP-Anforderung tatsächlich landet. Wenn nur ein Glied in der Kette von Computern, die mit unserer HTP-Anforderung beschäftigt sind, unterbrochen ist, dann kann ein Fehler wie ein 502 einfach auftreten. Bitte wenden Sie sich direkt (am besten per E-Mail) an uns, wenn Sie auf 502-Fehler stoßen - Sie selbst können nichts machen, um sie zu bereinigen. Wir müssen dann mit Ihrem ISP und dem Hersteller der Webserver-Software in Verbindung treten, so dass sie den IP-Datenverkehr zwischen den verschiedenen Computern, die sie betreiben, überprüfen können. 502-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-Name
