502 Bad Gateway

I have been using the desktop app (Version 3.5.2-200) for Quickbooks Online on my 2012 MacBook Pro for over a year without problems. This morning when I launched the application I got a "502 Bad Gateway" error message. I have tried the following, to no avail:

• Logged on and off

• Downloaded and reinstalled a new copy of the application

• Waited several hours, in case the problem was on the server end and got resolved there.


All the "solutions" I've found pertain to users who access QB via a web browser. I don't have any trouble accessing my account using a browser, but I prefer working with the app.  Anyone have any suggestions?

Hi there, @papabeer.


It's nice to have you here in the Community. I'm here to help you get past the error 502 Bad Gateway that you receive and get you back on track.


Error 502 Bad Gateway indicates that the server was acting as a gateway or proxy and received an invalid response from the upstream server. In this case, you'll need to clear the cache of your browser to get this sorted out.


The keyboard shortcuts vary depending on the browser you're using:

  • Google Chrome: press Ctrl + Shift + N  
  • Mozilla Firefox: press Ctrl + Shift + P
  • Internet Explorer: press Ctrl + Shift + P
  • Safari: press Command + Shift + N

If you're able to access payroll through the employee's section, you can log out and close the private browser. Then, open the regular browser (Ctrl + N), and clear the cache.


Here's an article for the detailed steps:

How do I clear temporary internet files and cache?

Re: 502 Bad Gateway

This happened to me this morning. I cleared cache. Nothing. Not acceptable.

It would be a different matter if customer support could help. All they could do was send me here to troubleshoot myself???!!!


And, this comes on the heels of a 17% increase ... for what?!


Very frustrating.

Hi there, @AnneT.


Error 502 Bad Gateway is usually an issue with the browser itself. When you're encountering the error when visiting Intuit sites, the general troubleshooting steps provided by my colleague can resolve this unexpected behavior. 


We also provide articles and step-by-step tutorials for future reference while working with QuickBooks and can be used as your guide if you want to run the solutions in your available time.


Since you get the same result, I recommend reaching out to our QuickBooks Online Customer Support team again. They can initiate the screen share tool to help you get past the error quickly and get back to business in no time.


With regards to the price increase, we are committed to develop an easy and most efficient financial tool to deliver time-saving features. This includes tracking labor costs by project, direct bank feeds, and recording your taxable and non-taxable sales tax with new sales tax liability report.

Welcome to the Community, @elise123. I'm here to help with this error message.


First, I recommend clearing the app's cache with the following steps:


  1. Click Help on the navigation bar at the top.
  2. Select Reset App Data.




Cached files are stored to optimize loading times, but can cause unexpected behavior if too much data accumulates. For additional information on this process and other troubleshooting steps, please see the following article: QuickBooks App for Windows and Mac: General support.


Please feel free to let me know how it goes as I want to ensure you can get past this error. I hope you have a great rest of the day.

The fix from DavidSC also worked for me - cleared the 502 gateway error I was receiving in the QBO desktop app.
