Creatio AI integration issue - on-site deployment

Hello,

I have contacted customer support to enable the AI on my local deployment. I have made all the changes as mentioned by the support.
 

I have enabled co-pilot features.

I have set the system settings - IdentityServerUrl, DefaultExternalAccessClientId, IdentityServerClientSecret, IdentityServerClientId, AccountEnrichmentServiceUrl with respective values..

But when I am trying to use the AI seeing below error in the network tab:
 

errorCode: "IncorrectConfiguration"

errorMessage: "IdentityServer auth failed with [BadRequest] invalid_client\n" 

Something is wrong in the configuration but not sure what's wrong.. Can anyone help debug and fix the issue.. TIA

Note: I have already reported this issue with support, not heard anything yet. As this is a blocker for me so posting it here in hope to get a solution.
