Getting hresult: 0x8007054F error for any certificates

Joshua Hemphill 1

If I try to select any of the auto-enrolled domain-issued certificates for binding https, I get

An internal error occurred (Exception from HRESULT: 0x8007054F)

The certificate has the private key exportable, and it's using ECDSA521 and SHA512 cryptography. I'm not sure what else to do.

EDIT:

After trying many different certificate template settings, I've discovered this is happening with any certificate that requires CA Certificate Manager Approval for issuance... Even though it's been approved and is in the key store.

Although, now my other certificate that does not require that is having the same issue...

I'm completely at a loss.

If I create a fresh copy of the Web Server template, it works for a little bit, but then starts throwing the error again...

@Joshua Hemphill Did you get any other error messages? It is impossible to determine the problem based on this error message alone. and how did you use the auto-enrolled domain-issued certificates?

Hi @Joshua Hemphill

A certificate with an ECDSA521 key is not supported in IIS. I would recommend changing the algorithm to ECDH_P384. The SHA512 signature will be fine unless you have some legacy devices that will be connecting to the server.

You should not have any issues binding certificates which require CA Certificate Manager approval.
