Telgrambot stopped working, what should I do?

Question

API

For unknown reasons, the bot on VDS stopped responding to commands, what needs to be done to fix it?
What I already did.
1. I tried to change the address to the Webhook 2. I uploaded the new code and the database (I used the old one) from the Logi
backup copy (what's wrong here?):

Answer 1

This is a rep request from the getupdates method, not logs. We need specific details, at least a function that processes parsed requests.
