[Remote attestation] unable to verify quote sig in middleware server (SP)

473 Views

I'm getting the following logs from the intel middleware server:

Attestation server sent invalid signature - IAS is not authentic. Exiting...

CheckValidQuoteSignature(.) returning False.
Nonce is valid - IAS is authentic.

ProcessEPIDPseudonym(.) returning.
******* IAS is invalid!!! Bad signature or nonce
*****IAS Status Code: 7

This is for a production enclave, I have configured it to use the production SPID, IAS endpoint. My RKMod is the mod of the pubkey in https://software.intel.com/en-us/sgx-sdk/download. I'm not sure if that requires configuring if so to what. Thanks in advance.
