Not receiving OTP for Professional Registry

When try to register professional on the site https://hpridsbx.ndhm.gov.in/register, no OTP is being received.
Aadhar OTP is coming perfectly but Professional ID registration OTP is not coming. Please check and revert immediately.

Regards,
Manish

Attached is the screenshot after which I am not getting any OTP.

@Shubhanshu_Shukla Can you please help me on this?

I hope this is resolved.

Not resolved. It is saying Unauthorized ASA channel?

What link to be used to generate Professional Registry ID for sandbox?
