{"answer":"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.\n\nOption: 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]\nApplies when: Running `qwen serve` with --tls-cert/--tls-key using self-signed, private-CA or re-exported certificates\nSteps:\n1. openssl x509 -in cert.pem -out cert-plain.pem (drop TRUSTED CERTIFICATE form).\n2.
