Not able to log on - error message 504 Gateway Timeout. I have cleared history & ca che, but still getting that error message.

Let's fix this error so you'll be able to log in, @AidaA. 

First, try to check if your current browser is compatible with QuickBooks Online. You can use the browser health checkup tool.

Then, try to check if you can log in using other browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari 11 or newer (Mac only) and the like.

I'll appreciate if you can update me with the results. I'll be here if you need anything else.

C'mon Intuit. Your service is ridiculously crappy.  Almost two months after this first started cropping up, the Mac app still does not connect (web works fine). I've downloaded and re-installed with no luck. 

Don't insult us with useless fixes. Just correct the error and post an update to the App already.

Our product team is still investigating the bad gateway errors when logging in to companies using the QBO desktop app, David-Kohl. 

I'd suggest reaching out to our Phone Support Team so they can add your account to the open investigation. This way, you'll be added to the list of affected users and a permanent fix will be sent via email. 

Please log in to your account using a browser and connect with us from there. Here's how:

1. Go to the Help menu and click Contact us. 
2. Enter in the space 504 Gateway Timeout when logging in to QBO through the app. 
3. Select Let's talk.
4. Choose to either Call or Chat with us. 

Meantime, you can use our supported browsers when accessing your QuickBooks account. I appreciate your patience while we're working on with the error.
