Google API: Not a valid origin for the client: url has not been whitelisted for client ID "ID"

Question

I need help. I don't found an answer to my question. I tried googling and I tried asking on other sides but I never found an answer.

I'm working with the google API (Youtube data API) and I use the example code from the google side the code it works I'm pretty sure about that. I got an error when i try to start the Script:

details: "Not a valid origin for the client: "MyURL" has not been whitelisted for client ID "MyID". Please go to https://console.developers.google.com/ and whitelist this origin for your project's client ID."

error: "idpiframe_initialization_failed"

The problem i whitelisted my Website and it's accepted. i don't know what is wrong. What should i do to "whitelist" my Domain (It's whitelisted)

And another question. I did not search for an answer on this question before.

I think it's possible that I can use the code on Localhost, I think I must whitelist my localhost address or something like this. But whitelisting does not work.
