Comet backup completes with the error: RequestTimeTooSkewed

Symptoms

A backup job returns the following error:

PRODUCT_WARN: Can't access Storage Vault: Failed to locate bucket '************' on any known region - error code RequestTimeTooSkewed (error details: The difference between the request time and the current time is too large.) 

Cause

This error comes from an S3 server. There is a time difference between the backup agent (or Comet Core server, if this error appears in system logs) and the S3 server. 

The current time is used as part of authentication, so if the clock is offset, authentication will fail.

Resolution

Ensure the times are in sync across all devices.

• Windows and Mac devices have their own internal time synchronization applications. 
• Linux devices can install services such as NTP and RDATE to assist with time synchronization.
