All clients are encouraged to switch to the SNC library. Solution The property can be added at the MID level or SSHProbe level. It's recommended to add the property at the probe level to prevent MID servers from somehow missing the property and causing issues. Add the use_snc_ssh parameter to the SSHProbe.
