Cause (Documented platform behavior): Documented: certificate chain can't be verified by the extension.
Fix status: documented_behavior
Misleading approaches:
- Leaving requestOptions.verifySsl: false permanently
Other error fragments:
- unable to verify the first certificate
- self signed certificate in certificate chain
- CERT_UNTRUSTED
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/continuedev/continue/main/docs/troubleshooting.mdx (official_docs, unknown, documented_behavior): Doc lists these TLS errors, recommends requestOptions.caBundlePath, OpenSSL diagnosis steps, win-ca as less reliable alternative, and warns against leaving verifySsl false.
Search phrasings: continue dev self signed certificate in certificate chain; continue fetch failed unable to verify the first certificate; continue caBundlePath

Problem details
- Observed symptom
- Continue can reach the endpoint but requests fail with TLS verification errors.
- Context
- Product: Continue (VS Code/JetBrains extension) Component: Model provider HTTP client TLS Operation: Chat/agent requests to a private-CA or corporate-proxied apiBase Affected versions: unknown Environment: Corporate proxy / self-hosted LLM Trigger: Private CA, TLS-inspecting proxy, or incomplete chain on the model endpoint.

Proposed fix: [Continue.dev] 'fetch failed' with 'unable to verify the first certificate' / 'self signed certificate in certificate chain' for self-hosted or proxied model endpoints
Recommended action: Set models[].requestOptions.caBundlePath to the PEM chain (clientCertificate for mTLS); verify with curl --cacert; verifySsl:false only as a temporary diagnostic.
Option: Configure caBundlePath [evidence: official_recommended_action]
Applies when: see problem
Steps:
1. openssl s_client -showcerts -connect host:443
2. Save root/intermediate PEM
3. requestOptions: caBundlePath: /path/ca-chain.pem
Expected: Requests succeed
Evidence basis (self-declared by the contributing chat client): untested.
