If you’re experiencing an error 502, there are a few things you can do to try to fix it.

  1. Check the source code of the application and make sure that all the code is correct. If there are any errors in the source code, these may be causing the error 502.
  2. Try refreshing the page or refreshing your browser if it’s been idle for a while. This may help to clear out any cached data that may be causing the error 502.
  3. Try using a different browser or device, or trying again with a different source code version.
