Autohook suddenly stops sending messages

[SamaaElKomy]

After starting the Autohook and it's working normally, suddenly it stops sending messages yet in console logs it shows that it is still listing to the events and processing, it's just not sending the response to the sender, this happens may be after sending around 20 messages between sender and autohook.

and after sometime it becomes normal again and starts responding to messages again.

is this issue related to using the free twitter developer account, should I upgrade to another account type?
