Sorry, I did this but still error is coming.

settings.client.proposedConformance |= Conformance.GENERAL_PROTECTION

Hi Mikko,

I did what you suggested but still error is coming. Please find below my settings for client please check and suggest where I am doing mistakes.

Hi Kurumi,

I already change it to client.ciphering.security = Security.ENCRYPTION

but still same error is coming. Please help me to resole the issue.

Satish

Hi Mikko,

Now this issue has been resolved.
