Data points outside time range on graph, but there is on table

Hi from Russia. Sorry my english.
Im new home user of influxdb and grafana.
1 week worked good. But after this weekends there is error.
Data come in 1 point (10-90 parameters per sec) per 1 second.
ESP8266 → influxdb.

ERROR or BUG: data there is in table on dashboard grafana. But not visible or NO in graph.
esp8266: SELECT “value” FROM “bv” WHERE (“param” = ‘bvtek’) AND $timeFilter
telegraf: SELECT “usage_system” FROM “cpu” WHERE (“cpu” = ‘cpu-total’) AND $timeFilter

tail log:

Grafana community.grafana.com on graph OK. I think there is some problem with time zone on my notebook or grafana server.
