Hi @Madden
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Log in to your Azure Portal and check if there are any alerts or error messages under Cost Management + Billing. Also, see if there are any unpaid invoices that could be causing the issue.
If your card details are correct but still not working, try removing the card from your account and adding it back again. Sometimes clearing your browser’s cache or using a different browser can help with updating payment details too.
If that doesn’t work, you can try adding a different payment method, like a new credit card or PayPal, if that’s an option for you. You can do that in Cost Management + Billing > Payment Methods.
Next, check your subscription status in the portal. If the payment failed and caused your subscription to be suspended, you might need to make a manual payment to reactivate it.
If none of that works, I recommend reaching out to Azure Support for help. You can open a support request in the portal by going to Help + Support and selecting Billing as the issue.
