Failure loading Fiori services with Extension Project in RDE

Dear Experts,

I have configured River RDE with the ECC , Gateway of Embedded deployment. All the Custom OData services and Fiori Services  are accessible when creating a new project , and facing an Authorization Error when creating a New Extension Project. The screenshots of the configurations and the errors are added below.
