This is clustered HSM environment. (remote HSM servers)
When try to import the new cert, get a Java Exception (see attached screenshot).
com.ncipher.provider.nCCommunicationException: error (st=-32761): Module 4802-03E0-D947 doesn't exit
One of the HSM boxes was “down”. This was the box that was the default for our gateways so the error.
Release : 9.4
Component : RUNSCOPE
Set the working HSM box as priority box fixes the problem.
