Cannot connect to datasource InfluxDB

The InfluxDB API is running fine:

$ curl -sl -I http://myserver:8086/ping
HTTP/1.1 204 No Content
Content-Type: application/json
Request-Id: 6e88a0a0-5288-11e8-a203-000000000000
X-Influxdb-Build: OSS
X-Influxdb-Version: 1.5.2
X-Request-Id: 6e88a0a0-5288-11e8-a203-000000000000
Date: Tue, 08 May 2018 06:24:15 GMT

But I cannot add InfluxDB as datasource, it keep saying “Network Error: Bad Gateway(502)” when I click “Save & Test”

I leave Auth option blank as by default InfluxDB disables authorization (should it be turned on?)

Btw, I’m using docker to run grafana and influxdb:

You should create docker network where grafana and influxdb will be able to reach other.
Or publish app port and use host IP. Or start containers in host mode. Anyway docker networking doc will be good start point for you to understand pros/cons of all options.
