This can happen if KeyShot is left on overnight or you have not logged out correctly before restarting. KeyShot can save the previous authentication token's date and time, causing it to expire.
If you have not done so already, please restart your computer to clear the authentication token and confirm your computer's date and time match the current timezone you are in.
Also, be sure to check if your internet time is correct as well. Even if your computer's time is correct, if the internet time is wrong you can still get this error message.
If that fails, please send a copy of the cloud_auth_error logs and your KeyShot.log file to our team at email@example.com.
A representative will be able to help you solve this issue.
On a Mac OS they should be located in either:
- /Users/<Username>/Library/Application Support/Luxion/KeyShot
- ~/Library/Application Support/Luxion/KeyShot
