Grafana and InfluxDB at Docker - InfluxDB Error: Bad Gateway

Hi there,

I have Grafana and InfluxDB 1.8 installed in Docker on my Synology. If I now configure the InfluxDB in Grafana, this error is displayed.

grafana is on port 3000:3000 and influxdb is on 8086:8086

can someone tell me where the error is.

Thanks

I found the problem. I need to take the IP from the docker container.
