We have a website that resides at an HTTPS:// address (not sure if this is relative or not) but users have the ability to post their comments on their twitter feed using the API with HybridAuth.
When I run the ‘account/rate_limit_status’ api request it says that there is 300+ requests left but every so often we get the following error message when trying to post a tweet:
Update user status failed! Twitter returned an error. 403 Forbidden: The request is understood, but it has been refused.
