Seems like both tools only work for node object and do not work for IP Address/ Incident since version 10.50 (tested on Linux and WIndows). The launch actions were changed and generate a log in error when launch for IP address or incident object.
Has anyone come across it or found any alternative way to do it.
There is a QCR for somewhat related issue.QCCR1B16331.
I have found same issue in 2018.05, 2018.08 and 2018.11
Open Inventory > IP addresses > Choose an IP address > from a menu choose Actions > Node access > Ping (from server)" is not working.
