Deploy and Troubleshoot SSL for AIRec HTTPS

Scenario

Developers enable HTTPS for AIRec recommendation endpoints to secure API traffic and comply with enterprise security policies. After provisioning a certificate via Alibaba Cloud CAS and mapping it to AIRec, they frequently encounter browser warnings like NET::ERR_CERT_AUTHORITY_INVALID or validation failures caused by chain misconfigurations or domain mismatches. This guide details the deployment workflow and targeted troubleshooting steps.

Integration steps

1. Provision Certificate in CAS: Request or upload your SSL cert via the CAS OpenAPI.

POST https://cas.aliyuncs.com/?Action=CreateCertificate&DomainName=rec.example.com&CertType=DV

2. Deploy to Ingress Layer: Push the certificate to the SLB/CDN fronting AIRec.

POST https://cas.aliyuncs.com/?Action=DeployCertificate&CertId=cert-8a9b2c&TargetType=SLB&InstanceId=lb-ai-rec-01

3. Prepare AIRec Mapping File: Populate certificate_info.xlsx with exact columns: Domain, CertificateID, Protocol (HTTPS), Port (443). Ensure FQDN matches the AIRec custom domain exactly.
4. Bind Certificate to AIRec: Apply the mapping via AIRec CLI.

airec-cli domain update --instance-id ai-rec-prod --config-file certificate_info.xlsx --region cn-hangzhou

5. Verify Deployment Status: Confirm CAS deployment and AIRec listener activation.

GET https://cas.aliyuncs.com/?Action=DescribeCertificateStatus&CertId=cert-8a9b2c → expect Deployed. Test curl -I https://rec.example.com/api/v1/recommend

6. Run CAS Diagnostics: If Chrome shows ERR_CERT_AUTHORITY_INVALID, trigger chain validation.

POST https://cas.aliyuncs.com/?Action=DiagnoseCertificate&CertId=cert-8a9b2c&CheckType=chain_validation&Client=chrome

7. Remediate & Redeploy: If diagnostics report missing intermediates, upload the full PEM bundle and redeploy.

PUT https://cas.aliyuncs.com/?Action=UpdateCertificate&CertId=cert-8a9b2c&PEMChain=<server+intermediate+root> → repeat Step 2.

Architecture

CAS acts as the centralized certificate lifecycle manager, issuing, storing, and pushing TLS assets to the network ingress layer (SLB/API Gateway). AIRec consumes the deployed certificate by parsing certificate_info.xlsx, which binds the custom domain to the HTTPS listener. Client traffic terminates TLS at the CAS-managed gateway, which forwards decrypted requests to the AIRec backend. Troubleshooting flows from browser diagnostics back through CAS validation APIs to verify chain integrity, domain alignment, and listener propagation.

Prerequisites

• Active AIRec instance with a verified custom domain
• Alibaba Cloud CAS account with domain ownership validated
• Valid SSL certificate (PEM format) or CAS-managed DV/OV cert
• certificate_info.xlsx template from AIRec console
• RAM role with AliyunCASFullAccess and AliyunAIRecFullAccess

Common pitfalls

• Incomplete certificate chain: Uploading only the leaf cert triggers ERR_CERT_AUTHORITY_INVALID. Always bundle server + intermediate certificates in the PEM file.
• Domain mismatch in mapping: certificate_info.xlsx requires exact FQDN matches. Wildcards or trailing slashes cause AIRec to reject the binding silently.
• CAS deployment latency: Pushing to SLB/CDN takes 1–3 minutes. Testing immediately returns stale HTTP responses or old certs.
• Browser HSTS caching: Previous HTTP visits force HTTPS with cached invalid certs. Clear state via chrome://net-internals/#hsts before retesting.
• Missing intermediate CA in CAS: If validation fails during troubleshooting, ensure the issuing CA’s root is publicly trusted or explicitly uploaded to CAS.

Typical questions

• deploy ssl certificate to airec
• airec https not working
• certificate error after deployment
• browser warning on airec domain
• 证书部署到AIRec后报错
• AIRec配置HTTPS失败
• SSL证书不受信任
• verify ssl installation airec

Q: How do I deploy an SSL certificate to AIRec? A: You deploy an SSL certificate to AIRec by provisioning it in Alibaba Cloud CAS, pushing it to your SLB or CDN ingress layer, and binding it via the AIRec CLI using a certificate_info.xlsx mapping file. Ensure the FQDN in the file exactly matches your custom domain and that your RAM role includes the required CAS and AIRec full access permissions.

Q: Why am I getting certificate errors or browser warnings after deploying HTTPS to AIRec? A: These issues typically stem from an incomplete certificate chain, a domain mismatch in your mapping file, CAS deployment latency, or cached browser HSTS settings. Resolve them by uploading a full PEM bundle containing the server and intermediate certificates, verifying exact FQDN matches, waiting 1–3 minutes for propagation, and clearing your browser HSTS cache before retesting.
