Every WordPress user is familiar with different errors that may arise from time to time. A popular one among these is the 502 Gateway Timeout error. This error code implies that the server while acting as proxy or gateway got an invalid response from an inbound server when it was trying to meet the request. This error usually denotes an issue with the server or network, but it can also be a client-side problem. In this article, you'll find some of the best resolutions for it.
Ways to Troubleshoot 502 Gateway Timeout Error
You can resolve this problem using various methods. Here are some tried and tested solutions you should use as soon as you notice this error.
Reload the page
One of the simple fixes for this error is reloading the page. Press' Ctrl' + 'F5' to reload it. Sometimes, the server is overloaded, and a quick reload makes the site come right back. Apart from reloading, you can also paste the website URL in downforeveryoneorjustme.com. The website will let you find if the site is actually down or if it's an issue on your part.
Clear browser cache
On encountering issues like 502 Bad Gateway you can also try clearing your browser cache. It's a simple 502 Bad Gateway fix that often yields results. To clear browser cache on Google Chrome, tap the three-dots icon in the top-right part of the browser window. Locate the option of 'More Tools' and choose 'Clear Browsing Data.'
Check your WordPress themes and plugins.
Often, queries and scripts get cancelled by the server because of a bad code on your site. Misconfigured caching plugins also cause 502 errors. You can resolve it by deactivating your site plugins.
An easy method to deactivate is by going to 'Plugins' and choosing 'Deactivate' from the menu of bulk actions. Every one of your plugins will get disabled. Now, you can find the problematic plugin by activating all of them. Make sure to reload the site after activating each one of them.
Fix the DNS problem
A DNS problem like the domain not resolving to the correct IP can also cause a 502 Gateway Timeout error. To fix it, you can flush your local DNS cache. All you need to do is launch the command prompt and input 'ipconfig /flushDNS.' If it fixes the problem, you'll view a message displaying 'Successfully flushed the DNS Resolver Cache.'
Mac users can enter 'dscacheutil –flushcache.' Note that you'll not see any success message as Windows users.
