Why I am still getting "502 bad gateway" when I try to open some of my client files in the app? I thought you were supposed to have fixed this.

Hello mafortier,

It's important to me that you're able to access QuickBooks Online using the preferred method, whether that's a browser or one of the apps. As a cloud platform, Gateway errors pop up from time to time for the program, and in many cases you can troubleshoot yourself to resolve the error. If not, then our tech support teams can help by troubleshooting further and escalating the situation if needed. I'll walk you through some troubleshooting steps and let you know how to get in touch if needed.

My first recommendation in this case is to clear the app's cache. It's really easy to do and makes sure there aren't temporary Internet files blocking the app's functions. The steps are as follows.

1. Select Help from the top menu bar (Note: Not the (?)Help menu, but one above it).
2. Select Reset App Data.

If after completing that you're still not able to get past the 502 Bad Gateway error, I recommend uninstalling and reinstalling the app. The following article walks you through that as well as gives you the link to reinstall the app when you need it: QuickBooks App for Windows and Mac: General Support

Next, try opening QuickBooks in a browser. With this step, you can verify if the gateway error is only appearing in the app or if it's also appearing in the browser. If you're also seeing it in a browser, it could be something to do with your Internet. Resetting the Internet can help these situations or checking with an IT professional to make sure the website is permitted through your connection is also good.

Finally, here's the contact information to reach QuickBooks Online technical support. Agents are on standby and ready to help you resolve these kinds of issues, so don't hesitate to reach out.
