Orchestration-Connections created using User/Role '*PUBLIC' throw Error '401'

Hi all,

I'm trying to build a REST connection in DV with User/Role - *PUBLIC and Env - JDV920. When I try to test this REST connection it throws me a following error :

"statusCode": 401, "error": "ExternalRestService:callGeneric: External Call Failed External Generic Call Failed See Log For Details: 401 ".

Then I created another connection using User/Role : 'JDE login User' and Env - JDV920 and tested it by calling from Connector and it is working great.

I might be missing some security setup in JDE for User/Role: *PUBLIC . Can some one please help me to figure it out. I truly appreciate your help regarding this.
