Cause (Documented platform behavior): run-qwen-serve contains a TLS trust preflight (verifyWorkerTlsTrust probe) that analyzes the chain and emits gap messages with the expected worker handshake error and a fix.
Fix status: documented_behavior
Limitations:
- Derived from the published @qwen-code/qwen-code 0.24.6 bundle; not reproduced in this session.
Other error fragments:
- Every worker handshake to the daemon will fail UNABLE_TO_VERIFY_LEAF_SIGNATURE.
- Every worker handshake to the daemon will fail INVALID_PURPOSE.
- --tls-cert and --tls-key must be provided together (got only --tls-
Evidence (public sources, summarized; not reproduced by this contributor):
- https://registry.npmjs.org/@qwen-code/qwen-code/-/qwen-code-0.24.6.tgz#package/chunks/run-qwen-serve-IIXONFKO.js (official_docs, unknown, documented_behavior): TLS preflight builds gap messages: unheldSelfSignedLeaf (BEGIN TRUSTED CERTIFICATE not taken by NODE_EXTRA_CA_CERTS loader -> DEPTH_ZERO_SELF_SIGNED_CERT), leaf purpose defect -> INVALID_PURPOSE, broken PEM markers -> UNABLE_TO_VERIFY_LEAF_SIGNATURE, and requires --tls-cert with --tls-key.
Search phrasings: qwen serve tls-cert worker handshake DEPTH_ZERO_SELF_SIGNED_CERT; qwen serve self-signed certificate workers fail; qwen serve INVALID_PURPOSE serverAuth; --tls-cert and --tls-key must be provided together

Problem details
- Observed symptom
- Browsers/curl reach the daemon over HTTPS, but channel workers cannot connect; qwen serve prints a certificate diagnostic at startup.
- Context
- Product: Qwen Code Component: qwen serve TLS (daemon ↔ worker trust) Operation: Running `qwen serve` with --tls-cert/--tls-key using self-signed, private-CA or re-exported certificates Affected versions: @qwen-code/qwen-code 0.24.6 (inspected) Environment: unknown Packages: @qwen-code/qwen-code 0.24.6 (inspected) Trigger: Workers trust the daemon via Node's NODE_EXTRA_CA_CERTS loader, which does not accept some PEM forms (e.g. -----BEGIN TRUSTED CERTIFICATE----- from `openssl x509 -trustout`, markers not on their own lines); a self-signed leaf must itself be in the trust store; leaf certificates without TLS-server keyUsage/serverAuth EKU, or intermediates without CA:TRUE, fail purpose checks.

Proposed fix: [Qwen Code `qwen serve --tls-cert`] Channel workers fail TLS to the daemon (DEPTH_ZERO_SELF_SIGNED_CERT / UNABLE_TO_VERIFY_LEAF_SIGNATURE / INVALID_PURPOSE) though the daemon serves HTTP
Recommended action: Re-export --tls-cert as plain PEM (-----BEGIN CERTIFICATE----- blocks, markers on their own lines), issue the leaf with keyUsage for TLS server and extendedKeyUsage serverAuth, ensure intermediates have CA:TRUE, pass --tls-cert and --tls-key together, then restart.
Option: Re-export --tls-cert as plain PEM (-----BEGIN CERTIFICATE----- blocks, markers on their own lines), issue the leaf with keyUsage for TLS server and extendedKeyUsage serverAuth, ensure intermediates have CA:TRUE, pass --tls-cert and --tls-key together, then restart. [evidence: official_recommended_action]
Applies when: Running `qwen serve` with --tls-cert/--tls-key using self-signed, private-CA or re-exported certificates
Steps:
1. openssl x509 -in cert.pem -out cert-plain.pem (drop TRUSTED CERTIFICATE form).
2. Check: openssl x509 -in cert-plain.pem -noout -ext keyUsage,extendedKeyUsage,basicConstraints
3. Restart qwen serve with both --tls-cert and --tls-key.
Expected: The error no longer appears.
