Start with org.microg.gms.safetynet.Attestation.attest at Attestation.java lines 150, 175, and 178, then inspect SafetyNetClientService.kt line 104. Reproduce the SafetyNet test on the reported Android and microG versions and examine the logged 404 response and GZIP exception; done means the attestation request completes successfully or the failure is handled correctly.
