The protection key could not be found (hasp status 91).

Sometimes, Pythagoras cannot detect the license, resulting in one of the following error codes:

• Hasp Status 91 – Identity conflict due to session takeover

HASP Status Code: 91 – IdentitySharingViolation

MEANING
The session was terminated because another machine with the same identity credentials took over the license.
This occurs with identity-based licenses, which are tied to a specific user or device.
When a new session with the same identity starts on another machine, the first session ends automatically.

SOLUTIONS

• Check the Idle Timeout or Session settings in the Sentinel License Manager:
  • Go to http://localhost:1947/int/config_to.html
  • Set the maximum value to 4320 minutes (72 hours).

1. Check if the license is already active on another machine.
   Ask users if someone else is using the same license.

2. Ensure there are no duplicate identities.
   Avoid logging in with the same identity on multiple devices at once.

3. Restart the software and try reconnecting.
   Sometimes a session remains 'stuck' and isn’t immediately released.

4. Contact the software provider about a license that supports multiple identities.
   A multi-seat license may be required.
