I have created an SMS app using JWT authentication method, which is still working excellent in sandbox environment. After fulfilling all the requirements, my app got approved for production environment but, when I try to run it using postman, first time it shows "error code CMN-405" (login to extension is required) and then I execute it again without any changes it shows "error code OAU-213" (invalid token/token not found).

I tried to delete older production JWT and re-initialize new production JWT but nothing changes. I am facing all these PRODUCTION ONLY IN PRODUCTION environment NOT IN SANDBOX environment
