[SOLVED] How to connect Chronograf 1.7 to influx 1.7.2 (openhabian)

I gotet this message from Chronograf :
level=error msg=“Failed to retrieve database version” error=“request to backend timed out”
level=error msg=“Error message Error contacting source” component=server http_status =400"

All are ok!
Don’t made changes: influxdb.conf

# Determines whether HTTP endpoint is enabled.
# enabled = true
# Determines whether the Flux query endpoint is enabled.
# flux-enabled = false
# The bind address used by the HTTP service.
# bind-address = “localhost:8086”
