Current config.ini is:

[influx2]
url=http://localhost:8086
# For influx v1.x please use "-" as a value
org=keenetic
# For influx v1.x please use "username:password" as a token
token=blah123
timeout=6000
# For influx v1.x DB name
bucket=keenetic
[keenetic]
skip_auth=true
admin_endpoint=http://192.168.1.1:79
login=user
password=password
[collector]
interval_sec=60

I also tried with: admin_endpoint=http://192.168.1.1 or admin_endpoint=curl http://192.168.1.1:79/rci

result was the same. From the host whom contains the docker machine I can access the :79 and 80 port:

$ curl http://192.168.1.1:79/rci | jq .system.hostname

"Keenetic"

I have tried 2.0.0 version and the latest both. My Keenetic OS is the following version:

Current KeeneticOS version: [3.5.10]

Could you please give me a clue?

@yagza you have a connection issue to influxdb, not router
