A "Verification Failed" message is used in various contexts which could be either a communication issue, or a problem with your account or a payment method.
Use the document Add a payment method to your Apple Account - Apple Support to review your payment methods such as credit or debit cards. Problem methods will usually have a notice in red lettering below them. The article If your payment method is declined in the App Store or iTunes Store - Apple Support has some information about declined payment methods as well as a link at the end for contacting Apple about payment issues.

Sometimes VPN use can cause problems. If you are using one, uninstall it.
If those don't resolve the problem, I suggest you contact Apple:
Contact Apple. Click here --> https://support.apple.com/choose-country-region Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
