Hi @artembondar,
I have just tested this on my end and was able to reconnect the connection.
It looks like the error is stating that the credentials you provided are incorrect.
Have you made sure that your tenant domain, client ID, and client secret are using the correct values?
If you believe they are correct and that the issue continues to persist, could you send me a direct message with your credentials and ping me here when you’ve done so?
Cheers,
Rueben
