Fix 502 error (easiest to toughest)

It could be a network connection issue

  1. One reason why 502’s occur could be due to bad IP connection and if this is the issue, refreshing the webpage should solve this temporary problem.
  2. Still here? Try closing all open tabs and active browsers and start afresh. If this is a network issue, this should solve your temporary problem. Still here? Try restarting your network equipment. Next, try opening your site in a different browser.
  3. If you are still here, try clearing your browser cache and cookies. To do that go to the three dots option at the top right corner of Chrome. Click on more tools and then on clear browsing cache.
  4. Next, try flushing your DNS. In windows, press the windows and R keys simultaneously and run the cdm. Now add this code:
ipconfig /flushdns

It could be because of CDN

  1. Disable your CDN temporarily. If you are using a free CDN, then this step is a must for you.
  2. If you are using the free “CDN enabler” plugin, deactivate it and then check. If your access to Dashboard has been locked, rename the plugin folder from to”cdn-enabler” to “cdn-enabler_old”. All plugins connected with your CDN will also get disabled.

Incorrect plugin or theme code

  1. Deactivate all the plugins. Does your site still show the error? If yes, you have to manually activate every single plugin and check your site every single time. If you have a hundred plugins, you need to do it a hundred times.

Find the faulty plugin and replace it with its alternative.
