Verification site failed to process

To the administrator of the verification site,

I attempted to verify a JSON certificate issued in BlockcertsV2 format on the verification site (https://www.blockcerts.org/), but received the following error message and was unable to verify it.

Message:
Not a valid Blockcerts credential. Please check with the issuer or recipient that has provided this credential.

I am reporting this issue to you in case there is a problem.

Best regards,
