Hey team, I’m having an issue registering my node after the 1.25.0 upgrade and I believe it’s caused by an invalid PCK certificate being served by your PCCS for my platform.

**The problem:**

Your PCCS ([pccs.scrtlabs.com](http://pccs.scrtlabs.com)) is serving an invalid PCK certificate for my platform’s FMSPC 30606A000000 (Intel Xeon Silver 4314, Ice Lake). When using your PCCS, DCAP quote

verification fails with SGX\_ERROR\_UNEXPECTED / “The provided certificate was invalid”. Switching to Intel’s PCS directly resolves the issue

Because of this, I can’t generate a valid attestation using your PCCS, so I can’t get my registered machine ID back:

- **Registered machine ID (via scrtlabs PCCS):** b4cdc2e6620dfd8c5d565041284714c38079c74c ✅ Known

- **Machine ID via Intel PCS:** 75d521f1ce4a826d3ee44cecf0b087003235cef1 🚫 Not known — chain rejects registration

**The ask:**

Could you refresh the PCK cert for FMSPC 30606A000000 in your PCCS? Once it’s serving a valid cert for this platform, I can regenerate my attestation with the correct machine ID

and complete registration.

Happy to provide any additional diagnostics. Thanks!
