How to fix Twitter API error (89 Invalid or expired token)?

Question

PHP

Hello, I set myself Twando for twitter, purely for the sake of sending thanks to users for their subscription. But often I get an error 401 (89 Invalid or expired token) how to deal with it?
If you manually log in again through Twando in your application, then the error disappears for a while ...
The third day I'm looking for information and all to no avail ...
Please tell me.
Thank you!

If this will make life easier for someone in the future (you never know), then the error occurs after the cron task is triggered, after which re-authorization in the application is needed ...
