When I try to access my QuickBooks online on my laptop a 504 gateway time out

Hi there, 

You've reached the right place for help. I want to make sure you're able to access and use QuickBooks without issues. 

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.  

If you're using a browser to access QBO, I recommend clearing cache and cookies. Doing this helps by fixing most issues the site may be having. Here's an article which shows you how to do that: How to clear Cache and Cookies.

After following the steps above, proceed with logging into your account and let me know what happens. If you're still having issues. I recommend contacting our support team using this link here. Our support team will be glad to look into the issue much further.

Let me know if you have other questions. I'll be here to help. :)
