Hi @saugat-nepal ,

Thanks for using FusionAuth.

Is this the process you are trying to do? https://min.io/docs/minio/linux/operations/external-iam/configure-openid-external-identity-management.html

Or is there another document you are trying to work through?

When using FusionAuth as the identity provider for a third party piece of software, it's often helpful to turn on debugging (under Application -> Your Application -> OAuth, then turn on Debug enabled). Then go through your login process. Then check the Event Log, under System -> Event Log. This should give you additional information about the handshake and OIDC process.

Please share those logs here (please remove any sensitive information from them) and we'll see if we can help.
