Client Authentication is missing even after logging in using EOS errors.com.epicgames.common.client_auth_required

I have been trying to create a channel under Voice Admin System of EOS , it requires a Client Unique ID and gives a channel credential under the created session.

Everything works fine but it is failing due to client Authentication missing, even when it is logged in.

Tried changing Client Policies but for some reason it is still throwing the same error as above.

Help me out on this anyone? or anynone :saluting_face:
