Hello Ricky,

As the packets fail step #5 there either is an issue with the sequence number (which should be ascending at all times) or the supplied ifIndex- number in sFlow packets. Unfortunately, we can't provide device-specific-support and as the target device seems to be sending incompatible packets to PRTG, the sFlow sensor will not work.
Please reach out to the vendor but yes, the sFlow Tester must work before you might see corresponding data within PRTG.
