Sometimes nothing is sent

[lapinvert]

I have a python script that calls telegram_send.send(), that is executed each time I add a new entry in the database.
It works most of the time but sometimes not, and I have no idea why.
The code is pretty simple, I just call it every time. But I see in database that for some entries, it didnt send the message.
Is there any way to debug it? Any log file maybe?
