Hello loocar,

If you are using the DEV environment you must access the environment with Base URL:

https://api.trustedservices.intel.com/sgx/dev

Your SigRL URL becomes: https://api.trustedservices.intel.com/sgx/dev/attestation/v4/sigrl/0000xxx

Sincerely,

Jesus G.

"I get 200 but body is empty. Why?"

That's how it is supposed to be.

When you get status 200 OK there are two possible cases: SigRL exists or SigRL doesn't exist. If SigRL exists then the Base 64-encoded SigRL will be in body. If SigRL doesn't exist then the body will be empty.

It's written in Page 9 of the IAS spec (§§ 3.1.2-3):
