Unable to create Health ID for HFR Admin

Greetings,

We’ve been trying to create a HFR Health ID, but we’re unable to do so. The registration form shows the user details after entering aadhar and mobile number, but when we’re trying to verify the entered email ID, it shows an error preventing the verification to continue. Here is the OTP sending API and the error it responds with:

API URL:
https://hpridsbx.abdm.gov.in/api/v2/account/email/verification/send/otp
:
Status code : 522

Error:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /api/v2/account/email/verification/send/otp .

Reason: Error reading from remote server
