Meaning
AWS rejected the request because the client time is out of sync with AWS.
Causes
- Client clock is skewed
- Stale signed request replayed
- Long delays between signing and sending
Fixes
- Sync system time using NTP
- Resign the request and send immediately
- Avoid reusing old signed requests
Example
Request has expired: 2026-02-06T01:20:00Z is now earlier than 2026-02-06T01:25:00Z
FAQ
- How much clock skew is allowed?
Only a small window. Keep time synced with NTP. - Will retrying without syncing fix it?
Usually not. You must correct the time.
