These troubleshooting steps are based on the original report. The issue still needs to be reproduced, and a fix has yet to be confirmed.
Identify the failed hostname and inspect its certificate issuer and chain from the Harness environment. For a managed HTTPS inspection proxy, verify the CA and fingerprint with its administrator. Add trust through the runtime's supported mechanism and repeat the request with certificate verification enabled.
