Thanks for visiting the Community, @mahmoud2. I'd want to make sure I'm providing you with the correct resolution to your concern.
We've previously received a report such as this when trying to subscribe to QuickBooks but it's already been resolved. If this is what you're trying to do, this can be resolved by adding a new different company address in the company settings page. Here's how:
Click the Settings menu (gear icon), then click Accounts and Settings.
In the Company tab, click the Pencil icon to make changes in the Address section.
Add a new completely different address in the field.
Once done, try running the card again. If you're referring to other tasks, It would be helpful if you can tell me more about which page or what are you trying to process when you received this error code? Any additional details that you can add can help me better in resolving your issue.
