We've updated to 9.4 running latest patch level.
As best as we can tell we've configured a network with mult-subnets.
Perform scan, and nothing from the other subnets.
A bit more, found some probe logs and yes ICMP is detecting devices in the other subnets, however is not creating an asset or scanning for SNMP results......
We logged a ticket with Kaseya, but they have not been able to work it out. We found an article from way back suggesting moving the probe to a different agent. We did this and it detected them all.
