I have setup OKTA login in React App, and everything works fine in local host. when the application is deployed in PCF, the application is redirected to OKTA login page as expected, but after entering the credentials it is redirecting back to application to the callback url, but it results in nginx 404 not found. the redirect url will be something like ‘https://app.domain.com/callback’. here the callback is not found whereas it works in localhost. any help/suggestion appreciated.
