We Use Github OAuth Apps to use Github APIs. We have enabled TOTP to handle authentication. Suddenly today we were being throttled while trying to do authorization with TOTP. Message was We were unable to authenticate your request because too many codes have been submitted. Please wait a few minutes and contact support if you continue to have problems.

Even though Error was gone after around half an hour. I am curious what could be the reason for this. I searched online and also read Github doc on rate limit. I don’t see this error anywhere.

Thanks for any suggestion you might have.
