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.
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...
