The token getting refreshed before 24 hours

We are needed help because the token getting refreshed each 1 hour or less. How Can We procede to this situation? Someone faced this problem before?

We are doing the refresh each a hour but after sometime (We dont know when and why) the refresh token became invalid and We can not able to request another.

Thank you in advanced.

Tokens don’t self-refresh; generally when this error is seen, it is due to a different process or thread refreshing the token and not supplying the new one to the first process.
