No data last 5, 15 or 30 minutes

I am having a small issue when I select quick ranges from last 5, 15, 30 minutes but if I select range with int that time I see data has I have added a few screenshots with my issues I am curious if anyone else has seen this issue

Grafana Version 6.6.2
Influxdb Version 1.7.10

What is the query being run?

sorry query below

“SELECT non_negative_derivative(mean(“bytes_recv”), 1s) *8 AS “rx”, non_negative_derivative(mean(“bytes_sent”), 1s) *8 AS “tx” FROM “net” WHERE (“host” = ‘fw1’ AND “interface” = ‘vmx0.999’) AND time >= now() - 15m GROUP BY time(1s) fill(null)”

You mean you have specified a fixed time range? Usually one would use WHERE $timeFilter I am not sure what will happen if you combine a fixed range with a dynamically imposed time range.
What does the query inspector show for the failing and working time ranges?

find my issue it was that ntp was not running on server and time was way off started ntp service and 5,15, 30 mins started to show correctly
