Firewalls should always be active since they help block malicious threats from reaching your device.
Not for amateurs, this is one of the more controversial methods on this list. The browser’s cache stores important information that can become corrupted over time, so clearing this and re-attempting to connect to the server may do the trick. Major browsers will make this option easy to find within their respective settings menus and most will simply let you enter a query using a search field to find the option. If refreshing the browser a few times doesn’t work then clearing the browser’s cache may help. It sounds too simple to be true, but in some cases where the server is overloaded with requests, sending a few more requests by refreshing the browser a few times can sometimes help reset the connection between the device and server, allowing you to resume browsing. There are a number of key steps that users can take to attempt to fix a 502 Bad Gateway error. Slower queries can also cause this problem. Server software timeouts: The error can also show for users when a web server takes longer than expected to return a request, and the caching tool reaches its time values.
An ISP, for example, may have decided to block a certain web address. Network errors: There is a multitude of potential networking errors that may occur, including potential DNS issues, routing problems, as well as issues relating to your Internet Service Provider (ISP). This can often occur with DDoS protection layers, which block requests from content delivery systems and cause the network to stop slowly.įaulty programming: Often enough, a glitch or coding error in a website's code might result in requests not being answered correctly, sparking the 502 Bad Gateway error to show up.
However, several firewalls can often go further than you’d like and inadvertently treat a massive influx of legitimate users as an attempted cyber attack. Request blocked by a firewall: With cyber criminals finding more and more ways to breach corporate networks, firewalls continue to play a key role in stopping them in their tracks.
