Welcome to the Community, @gary15.
I've checked here and no longer found any open ticket about the 504 Gateway Time-out error message. I recommend you follow the basic troubleshooting provided by my colleague above to fix the problem.
Since the Community is a public forum, I'm unable to review the account without asking for sensitive information. If the error continues, I suggest reaching out to our QBO Customer Care Team.
One of them will need to take over and ensure you'll be able to get rid of the error. Here’s how:
- In your company, go the Help icon to choose Contact Us.
- Type the issue/topic under the What can we help you with section and then hit the Let’s talk button.
- Scroll down to select the Get a callback option and then enter your contact information.
You can reach them within this time: Monday to Friday from 6:00 AM – 6:00 PM and Saturday 6:00 AM - 2:30 PM PST.
I’m attaching an article with detailed lists on the latest enhancements added to the product. Aside from that, it contains some links on how to efficiently run the business: QuickBooks Blog.
Please know the Community has your back. If you have additional questions, click the Reply button and post a comment. I’m here ready to assist further. Enjoy the rest of the day.
