Hi there, @3i_ai.
There are no ongoing investigations about users getting error 404 when trying to tap the Buy now button in QuickBooks Commerce. I'm here to ensure you'll be able to integrate the application you need into QuickBooks Online (QBO).
I appreciate you for performing the basic troubleshooting steps to isolate the issue. Since the error continues, you can try using another supported browser aside from Chrome and Firefox. You can check out this link as your reference: System requirements for QuickBooks Online, Accountant, Payroll, and QuickBooks Self-Employed.
Alternatively, you can purchase the application through this link: QuickBooks Commerce.
If you're getting the same result, I would recommend reaching out to our Support Team for further assistance. A live representative can look into your account securely and investigate this error message.
