Notarization: Error 65

Hello,


when I try to staple the notarization ticket to my dmg, I get the following error:

xcrun stapler staple -v dist.dmg

[....]

Downloaded ticket has been stored at file:///var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/2624b6a9-38a2-4621-9b75-55925bdedecc.ticket.
Could not validate ticket for /Users/timafh/Documents/project/dist/dist.dmg
The staple and validate action failed! Error 65.


I cant find informations about this situation. Can anybody help me out?
