I have Quickbooks online. I get 502 bad gateway message when I sign in using desktop app. I can sign in when using a browser but prefer the app instead. What to do?

Hi there,

You've reached the right place for help. Don't worry, I'll help get to the bottom of this.  

The 504 Gateway Timeout error is an HTTP status code means that one server did not receive a timely response from another server that it was accessing while attempting to load the web page. This usually occurs when one of the two servers is down or not working properly.

To fix this error, you need to clear cache on the QuickBooks app. Here’s how:

1.     Go to Help at the top corner of the screen.
2.     Choose Reset App Data.  

Give this a try and let me know how you make out. If you need further assistance, don't hesitate to reach out to our support team using this link.
