Registering Quickbooks Desktop Pro 2021 on Windows 2019 Server gives Gateway 504 time-out

Glad to see you here, @dbadmin2021,

Thanks for getting this to our attention and sharing the things you've done to resolve the problem.

The reason why the troubleshooting steps you've tried didn't work is due to the an ongoing issue for QBDT UK accounts. Our engineers received a number of reports with users getting 504 Gateway Time-out error when activating or registering the program.

The fix for the issue is still in the works. Our engineers are working internally so we can't provide the exact turnaround time on when a resolution is released.

Instead, they send live updates about the status of the investigation through email. If your account  is not yet added to the notification list, please contact our Support Team using these steps:

1. Open QuickBooks and click the Help menu.
2. Select QuickBooks Desktop Help.
3. On the pop-up screen select Contact us.
   
4. Click the Search for Something else button then type your concern in the Ask us anything box.
5. Hit Search then scroll down to get your contact options.

Provide the investigation number INV-55656 to our representatives for easier tracking.

You can also try this workaround that we got from our engineers. Go to the Help menu then About QuickBooks Desktop. When you see the green logo, press CTRL + R + P on your keyboard.

We appreciate your patience while the resolution is being worked on. This thread will remain open for any updates and inquiries. You can also tag me for other concerns in QuickBooks. Have a good one!

Hi Jen_D,

Many thanks for the prompt reply!

I'll see if I can register my email address with support for updates.

Although, this is issue was handed to me after a colleague had been struggling with it for many days now, so hopefully the fix is very close.

Kind Regards

.... the manual registration worked!

Thanks again.
