8 Ways to Fix the 502 Bad Gateway Error
Having a 502 Bad Gateway error can be frustrating, as it disrupts access to your website and impacts user experience. Resolving the issue promptly is crucial for minimizing downtime and maintaining a seamless browsing experience. Below are eight effective methods of how to fix 502 bad gateway.
Reload the Webpage
One of the simplest solutions to a 502 Bad Gateway error is to reload the webpage. Sometimes, the error is temporary and caused by a brief server glitch. By refreshing the page, you can clear the temporary issue and regain access to the site.
Verify Server Uptime
If reloading the page doesn’t resolve the error, the next step is to verify the server’s status. Be sure that the server hosting your website is operational. If the server is down, it could be experiencing maintenance or an outage. In such cases, waiting for the server to come back online or contacting your hosting provider can help resolve the issue.
Clear Browser Data
Clearing your browser’s cache and cookies can also fix a 502 Bad Gateway error. Over time, stored data in your browser may become outdated or corrupted, leading to conflicts with the server. By clearing this data, you help your browser load the most recent version of the website without any cached errors.
Use Private Browsing Mode

Private browsing mode doesn’t use cached data or stored cookies, which can sometimes cause the error. If the website loads successfully in incognito mode, the problem may be related to cached data in your regular browsing session.
Reset DNS Settings
DNS misconfigurations can also lead to a 502 Bad Gateway error. Manually resetting your DNS settings or switching to a different DNS server can resolve the issue. Additionally, flushing the DNS cache on your computer can clear any outdated or incorrect DNS information that might be causing the error.
Switch to Another Network
Testing the website on a different network connection can help determine if the issue is network-specific. If the error persists on your current network but not on others, the problem might be related to your internet connection or network settings. Switching networks or restarting your router can sometimes fix the issue.
Review Server Logs

This information can help you or your hosting provider troubleshoot the problem more effectively.
Inspect Website Add-ons
Finally, incompatible or faulty website add-ons, such as themes or extensions, can cause a 502 Bad Gateway error.

Updating or replacing the conflicting add-on can restore normal server operations and resolve the error.
