I’m trying to make a ping to a list of hostnames using n8n. When I try to process all a matrix of hostnames to make a ping (execute command) to each of them, it only runs the first one. I tried to change ips and hostbnames to a false one in order to make all of them fail. But once a run the workflow, it only sends one message, and not one for each of them
My workflow:
