status code: 429, error: Number of allowed API requests per minute exceeded

Hi there,
I want to ask for some assistance with an issue I am facing.

I am sending a request to the following URL:
 https://<client_name>.zendesk.com/api/v2/tickets/2426492/metrics.json

And I got the 429 error message that, according to Zendesk's docs, means too many requests. The Retry-After header specifies that you can retry the API call in 93 seconds. Your code should stop making additional API requests until enough time has passed to retry.

I did it; I stopped my code and made additional requests within 93 seconds; I tried even sleeping for 100 seconds but still got the same error

That is what I get:

Any idea how can I solve it?
Thanks!
