(Wc-34737-4) PlayStation 4?

What can I do to prevent this error code from occurring

What can you read there? Your account details are invalid

Enter your credit card / account details correctly

or

Use a credit / debit card that is still valid.

True but not entered everything correctly

I still have it

Is it still valid, the card? It's easy to overlook.

Well, what is written about it, of course…

Can't be, there's an error message - there's something about support below

Yes until 12/24

Oh! Then search through the support or contact the hotline, they definitely have one.

But is not invalid

I thank you 🙏🏽

It is there.

Yes, I'll go to support

That's not true but I entered everything and everything is correct and the card is not invalid

Apparently it does. Either you entered the data incorrectly or the card is blocked.
