Hello @Witsanu Ratreeswad ,
The Reason that you are blocked because, it appears that authentication for your Azure tenant has been temporarily disabled due to a recent security incident.
To resolve this, we reached out to the Product Group team internally. Our Team unblocked/re-authenticated your tenant.
Thank you for confirming that you are able to access the tenant.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
