I’m new and I don’t know about rate limit . just when i search for problem in google so I discovered the reason .if there any possibility to increase my rate limit .
Please see this link:
There’s also a form in that link which is the request to increase rate limit.
Moved to #help
Note that you cannot use this form to request a temporary exception due to accidentally exceeding a rate limit. Temporary exceptions like this aren’t available at all.
