I installed 3 SMG on VM for the latest version 10.6.1:
1 VM - Control Center
2 VMs - Scanner
The 1 VM scanner does not encountered any problem while the other scanner received that error.
Hope someone could help me in this problem as it is not a searchable problem and support cannot trace it.
The recent advise it to restart the problematic Scanner and do the syntax on Control Center cc-config database --repair
Thanks!
