Unable to link client to application in EOS product configuration

Hi, I have been trying to link the client that I created in my EOS dev portal product configuration to my product under the Epic Online Services configuration panel and I am getting the following error.

I would be grateful if anyone can help me out.

Hi, it sounds like a configuration issue. Can you provide more details about the error message you’re seeing? That will help in diagnosing the problem. Thanks

Troubleshoot by checking client application compatibility and ensuring that EOS product configuration settings are adjusted correctly. If the issue persists, please refer to the product documentation or contact support to resolve the issue.
