7209	"Mac notarization fails about 1/4 of the time: ""A timestamp was expected but was not found"""	Tom Goddard	Tom Goddard	"Our nightly builds on the Mac often fail because of a notarization failure when running the Mac codesign command.  The error message is ""A timestamp was expected but was not found"".  Our notarization code retries the codesign command but often it fails again.

Others have reported the same problem and found it to be firewalls sporadically blocking packets from Apple's timestamp server

The suggested solution is to get your network IT people to fix this, or to move you notarization to a network that doesn't have this firewall issue.
