Dont come checks with tax (laravel)

There is a back on laravel, which is a backend for the mobile app.

1. In the app, users scan checks
2. The following parameters for cheque recognition are sent to the tax office: fiscal savings, fiscal document number.
3. The data from the tax are stored in the database.

Now the data about the check from the tax office has stopped coming. Trying to change the endpoint - did not help. Maybe you need to restart the crown or something...
