Domain Verification Failed!

[bmarw]

Hi

I am working on integrating ONDC .We are buyer app. I followed this document.
https://github.com/ONDC-Official/developer-docs/blob/main/registry/Onboarding%20of%20Participants.md

I have reached till step number 5 and Now when I hit below url.with proper request body.
https://staging.registry.ondc.org/subscribe
What could be the reason for this. I used Java utility to generate the content inside the page.

I get
{
"message": {
"ack": {
"status": "NACK"
}
},
"error": {
"type": "DOMAIN-ERROR",
"code": "129",
"path": null,
"message": "https://comedia.in : Domain verification is failed "
}
}

I have proper request body.

Any help would be appreciated.

I don't know if content of my message body that I am sending is wrong or html page ondc-site-verification.html content field is wrong.

Regards
Bhanu

Steps I am doing:
I hit the local URL(Java Application)

1. http://localhost:8080/get-keys
   I pick sign_private_key, and sign_public_key.
   2.I run Util Method in java class
   https://github.com/ONDC-Official/reference-implementations/blob/main/utilities/on_subscibe-service/java/src/main/java/ondc/onboarding/utility/Utils.java

 public static String sign(byte[] privateKey,byte[] message) {
        // initialise signature variable
        byte[] signature = new byte[Ed25519.SIGNATURE_SIZE];

        // sign the received message with given private key
        Ed25519.sign(privateKey, 0, message, 0, message.length, signature, 0);
        return  toBase64(signature);
    }

"message": {
"request_id": "ccfce272-13c3-4ca4-a070-64769f5df2a66"
and use above request_id to sign the request.
I get a value and place it inside content section of html page.

I have made sure that
"key_pair": {
"signing_public_key":"MnG3p1Cp5ofZEDE6cnOGeYX1EulMZSPHWTBRdzy/INk=",
is corresponding to the private Key that I am using to generate the content in html page,

I also feel there might be a bug in Utility method.
Because when I run verify on genrated signature it fails locally for me,

What can be done to fix this
