Hi there, keith62,

We encourage everyone to access their QuickBooks Online (QBO) account through web browsers. This is to get the most out of QuickBooks experience.

Our Product Team is investigating the bad gateway error when loading companies in the desktop app. I recommend contacting our QBO Technical Team so they can add your account to the investigation (INV-35885). This way, you'll be able to receive an update regarding the issue via email.

Here's how to get in touch with them:

1. Log in to your account using the supported browsers.
2. Click Help (?) at the top right.
3. Select Contact Us to connect with a live support agent.
   
4. Enter a brief discussion of your concern, then click Let's talk.
5. Choose a way to contact us.

I appreciate your patience and understanding while we look into this matter.
