Packets arrive to the server, but exporter is not visible in the application.
Solution
Check if destination port set on your exporter matches listening port in the NetVizura configuration (Settings > NetFlow Settings > Configuration > NetFlow Collection port)
Check your server firewall
If none of the above solves the issue, capture your traffic in a pcap file (10 minutes of traffic or more) and send it to the support@netvizura.com
To create a pcap file:
in Windows OS, you can use program called Wireshark
in Linux OS, you can use the tcpdump command, for example: tcpdump -nn -w netflow.capture.pcap -c 35000 -i eth0 port 2055
