Hi Team,

I am facing an issue during authentication from the Android Registration Client.

Environment Details:

- MOSIP Version: 1.2.0.2
- Registration Client: Android
- Authentication Flow: IDA Authentication

Issue:  
Authentication using the Desktop Registration Client is working successfully. However, authentication from the Android Registration Client fails with the following error:

`Errors=[{errorCode=IDA-MLC-018, errorMessage=Salt for the given ID not available in database}]`

Additionally, in the Credential Service logs, I can see the following error:

`credential encryption failed`

`io.mosip.credentialstore.exception.DataEncryptionFailureException: IDR-CRS-013 --> Not allowed to generate new key pair for other domains or not allowed to generate base key.`

Observations:

- The UIN data is available in ID Repo.
- Desktop authentication works successfully for the same environment.
- The issue occurs only for Android client authentication.

Could you please advise how to resolve this issue?

Thank you.

Best regards,  
Gaprin
