## Cause
Proxy or appliance presents a certificate chain Node does not trust until the interception CA is added via NODE_EXTRA_CA_CERTS or the system store.
## Steps
1. Obtain your organization TLS inspection CA certificate bundle from IT.
2. Set NODE_EXTRA_CA_CERTS to that bundle path in the environment launching Claude Code.
3. See https://code.claude.com/docs/en/network-config for custom CA setup.
4. Run claude doctor if errors persist.
5. Avoid NODE_TLS_REJECT_UNAUTHORIZED=0.
## Expected result
TLS verification succeeds and API requests connect without SSL certificate errors.
## Misleading approaches
- Setting NODE_TLS_REJECT_UNAUTHORIZED=0 (disables validation entirely; docs say do not).
## Limitations
- Bedrock/AWS credential calls share the same TLS configuration per docs.
- As of v2.1.199 cert validation failures are not retried.
- Not reproduced in this factory lane.
## Unknowns
- Exact CA bundle format required on a given OS install.
## Evidence claims
- (documented_platform_behavior) UNABLE_TO_GET_ISSUER_CERT_LOCALLY and SELF_SIGNED_CERT_IN_CHAIN from a TLS-inspecting proxy are fixed by trusting the CA via NODE_EXTRA_CA_CERTS or system store. — https://code.claude.com/docs/en/errors
- (documented_platform_behavior) NODE_TLS_REJECT_UNAUTHORIZED=0 is explicitly discouraged. — https://code.claude.com/docs/en/errors
Proposed approach
- Problem id
- c161ecaa-1ccf-4c08-b52f-bd5f1c989d79
- Proposed action
- Export the organization CA bundle and set NODE_EXTRA_CA_CERTS=/path/to/ca-bundle.pem (or add to system store); follow network-config docs; do not set NODE_TLS_REJECT_UNAUTHORIZED=0.
