Hi **Na Li,
**
We came across a continuous Bad Request error stating “Operation on target UntilCheckApprovalRequest failed: Activity timed out”.
Based on the analysis, the request is not reaching the target endpoint due to a certificate validation issue during the SSL/TLS connection setup. We kindly request you to please check and ensure that the SSL/TLS certificate on the target endpoint is valid and up to date.
Once the certificate is renewed or corrected, please re‑run the pipeline from your end.
