cant specify marker position via address

Hi, I’m having problems creating markers.
When I try to write down the address to where the marker should point, i always receive error: https://developers.google.com/maps/documentation/javascript/error-messages?utm_source=places_js&utm_medium=degraded&utm_campaign=keyless#api-key-and-billing-errors
* The request is missing an API key.
* Billing has not been enabled on your account.
* The provided billing method is invalid (for example an expired credit card).
* A self-imposed daily limit has been exceeded.

But fact is, i have the api key, i’ve enabled billing, the billing method is ok, and i dont have daily limits.

Can you help me solve this issue?

Thanks
C
