Error Code 605

I downloaded my desktop 2025 product and copied the activation code. During activation it gave me the code and when I clicked on it, I got a 605 error code. So I tired typing it in and still got a 605 error code. I rebooted my computer, tried again and still got the 605 error code. I need this product to be activated ASAP. This is the first time I've ever had a problem with activation. What is going on? My OS is Windows 11. I had to go out and purchase a laptop with Windows 11 on it because TurboTax won't let us use Windows 10. And now I can't activate the product. I am beyond angry.
