Hi Shashikanth,
Thank you for posting your concern.
You may check on your end if you encounter one of the reasons specified on this
document why your refresh token is expiring. If upon checking you determine that you did not encounter the possible reasons said in the document, then I would suggest to reach out to the Oauth2 team via this
link. I routed you to their team because they are more equipped to check the issues and concerns related to the refresh token.
Regards,
