I'm trying to add a custom Netflow 5 sensor to our existing PRTG environment.
I have a working Netflow 5 sensor on one router (note that it's NOT custom), but I'd like to add the custom to a different router.
I've created it as instructed using the instructions in article: https://www.paessler.com/knowledgebase/en/topic/2143-can-i-add-custom-channels-to-standard-packet-sniffer-and-netflow-sensors
I've even just copy / pasted just the defaults in the article and it still fails.
What happens is when I click "Continue", the window closes immediately and goes back to my device list. Nothing happens. No new sensor shows up as added to the selected device, and I see nothing in the log files of the device either.
Any ideas what is going on?
