Authentication Error

I am trying to perform Auth. process after setting up api app. So after executing url “

getting below error.
{“status”:“error”,“errors”:[{“errorCode”:“UDAPI100500”,“message”:“Something went wrong… please contact us”,“propertyPath”:null,“invalidValue”:null,“error_code”:“UDAPI100500”,“property_path”:null,“invalid_value”:null}]}

Either the client ID or the redirect URL may be incorrect. Please verify your details against those in the app you created to ensure they match.
