@janjanson welcome to MyController forum. the forum responsive for Markdown language.
Looks like you have entered a wrong port number on the mycontroller.yaml file for the influx db. You are running influxdb on 8086 but on the configuration file it is set to 8080
you should have something like this
database:
metric:
disabled: false
type: influxdb
uri: http://127.0.0.1:8086 # must be updated with your host ip address
BTW, MyController supports InfluxDB 1.8.x or above. MtyController have not tested with influx db 1.6.x
