Connection Response 401 associated key not found error when linking KACE appliances (4313329)

When linking one KACE appliance to another, the user gets the following error when testing the connection:"connection response 401 associated key fingerprint not found"

Missing charecters/incorrect linking key.

This can occur when one of two things happen:

1. The managed linked appliance page does not contain a reference for the other appliance. KACE linking is a two-way trust between appliances. Therefore, each KACE appliance must have the other appliance's linking key in order for them to communicate.
2. The certificate from the wrong appliance is in the managed linked appliances page. Therefore, no trust is made since the linking key do not match the other. 

Things to check:

1. Make sure to use IP address or fully qualified hostname is entered when creating links.
2. Make sure that a specific user has the same username and password on both KACE appliances.
3. Check the hostname of the two KACE appliances and ensure they are correct.

Resolution:

   2.      From the appliance, click Settings | Control Panel | Linking KACE Appliance Settings.
