![]() This allows you to check if a browser extension is the source of the error message. In safe mode, the browser deactivates any installed plugins. If this doesn’t work, then start your browser in safe mode. The first step should be restarting the browser. If the error is actually only occurring for you, then check the functionality of your browser. Of course, if you can’t access any websites without the “Bad Gateway” message, then it’s obvious that the error has something to do with your computer, browser, or firewall. To check whether the error stems from other users or you, you can, for example, use the web service Down for everyone or just me?. The error could also be in your system - even if the status code indicates something else. Various versions from the past years are stored here. If you need to go back through the site’s history to find a working version, then the Wayback machine - from the nonprofit internet archive - can help. You should be aware, though, that you’re viewing an outdated version of the site. To load the cache page of the search engine, enter cache: in the search field and then the URL that you would like to visit (for example, cache:). Google saves websites for a time on its own servers and so can display an earlier version of the respective website. If the error is actually on the server side but you still want to access the content right away, there are also other ways to bypass the error message. Within your browser, you can display all of the cookies and remove only those that have something to do with the corresponding website.) Still receiving the same error message? Then clear your cache and cookies, as it could be that your browser didn’t truly reload the page and instead just accessed data from your internal storage (you don’t necessarily have to delete all of your cookies. Since such failures can also last for a fairly long time, reloading the page again is only really worth it after 15 minutes. If the problem is solved by doing that, then it means that the server was just temporarily overloaded. In most cases, it can be fixed by simply reloading the page. If you want to access a page and instead get the status code 502, there’s a high chance that the error isn’t with you. Browser error: Browser extensions can also sometimes cause errors with the display of a website and generate a 502 error.Communication error: Firewalls can cause errors on both sides of the communication (server and client) with the forwarding of requests.Certain requests will then not be answered correctly anymore, delivering a negative result instead. Faulty PHP programming: Occasionally, there’s an error in the website’s code.This means that an attacker is using a bot network to help overload the server capacity and provoke a system failure. The reason could be an unexpectedly high interest in the site or even a DDoS attack. Webserver overload: If a webserver reaches its limit, it can’t answer any more requests - the gateway then delivers the status code 502 Bad Gateway.In rare cases, servers can also be taken offline spontaneously - for example, when the content is in violation of a law. Server failure: The gateway receives a negative result if the target server has failed completely, among other things.The following reasons could explain why the infamous HTTP code is displayed: It’s also possible that you’re disconnected from your network. But it’s also possible that the browser being used has registered a 502 error where really none exists. In most cases, the bad gateway error occurs on the server side and can’t be fixed by the internet user. That’s why this error message is often so frustrating: It’s generally not at all clear at which point in the process the request encounters the error. In principle, all queries on the internet are forwarded via gateways. In this case, the first server functions only as a proxy or gateway. It’s delivered when the server, which is accessed via the main server, couldn’t forward the request. Next to the well-known 404 error (“ Page not found”), the bad gateway error is one of the most common error messages received when surfing the internet. The 502 error is usually provided with the addition Bad Gateway or as a “ 502 Bad Gateway Nginx”, “ 502 Bad Gateway Apache”, or “ 502 Bad Gateway registered endpoint failed to handle the request” message. The status codes also indicate where the error occurred - at least to users who know what the individual codes mean. On the flip side are the error messages: While 400 codes imply that the error lies on the client side, 500 to 511 codes mean that the negative result is the server’s fault. Instead, visitors simply see the requested website content. This status isn’t usually shown to users, though. ![]() The most common code is probably number 200: OK. The internet protocol HTTP generally provides status codes in response to queries.
