Cause (Documented platform behavior): OpenSSL's X509_V_ERR_CERT_NOT_YET_VALID/CERT_HAS_EXPIRED verification errors; OpenSSL master reworded the not-yet-valid text to mention an incorrect system clock (3.5.0 still says 'certificate is not yet valid'). Node exposes the same condition as error code CERT_NOT_YET_VALID.
Fix status: documented_behavior
Misleading approaches:
- Adding the provider's certificate to a custom CA bundle or setting verify=False — the chain is fine; the clock is wrong.
Limitations:
- Which OpenSSL release first ships the reworded message is not determined (present on master, absent in 3.5.0).
Other error fragments:
- certificate is not yet valid or the system clock is incorrect
- certificate has expired
- CERT_NOT_YET_VALID

Problem details
- Observed symptom
- Every HTTPS request fails certificate verification although the server certificate is valid and other machines connect fine; often right after a snapshot restore, sandbox resume or RTC reset.
- Context
- Product: OpenSSL (Python ssl, curl, git) / Node.js TLS Component: X.509 validity-period check Operation: HTTPS calls to model APIs from VMs/containers/sandboxes with a drifted or reset clock Affected versions: unknown Environment: unknown Exception: ssl.SSLCertVerificationError, httpx.ConnectError, openai.APIConnectionError Trigger: System time earlier than the certificate's notBefore (or later than notAfter).

Proposed fix: [OpenSSL / Python ssl / Node TLS] 'certificate is not yet valid' (CERT_NOT_YET_VALID) or 'certificate has expired' against valid LLM API certs — host clock is wrong (newer OpenSSL says '
Recommended action: Check `date -u` against a trusted source and enable NTP; don't install custom CAs or disable verification.
Option: Fix the system clock [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. date -u; compare with a reliable time source.
2. Enable chrony/systemd-timesyncd, or resync after VM/sandbox resume.
Expected: Error no longer occurs
