Hi @Adrian Juwono ,this usually indicates that the IP address from which the request is being made is not allowed to access the resource, or the configuration of your tenant is incorrect. Can you please try the following steps and let me know your results?
- Check the IP address restrictions in your tenant.
- Check the CORS configuration for your tenant.
- Check the permissions for your application.
If everything is configured correctly please let me know and we can open a support request.
Please let me know if you have any questions and I can help you further.
If this answer helps you please mark "Accept Answer" so other users can reference it.
Thank you,
James
