I have just installed Chronograf and Kapacitor using APT ([InfluxData - Package Repository](https://repos.influxdata.com/ubuntu)) on an EC2 instance on Amazon Web Services. Using default configuration for Kapacitor.

Ubuntu 14.04.5 LTS  
Chronograf 1.4.2.3-1  
Kapacitor 1.4.1-1  
Influxdb 1.5.0-1

But Chronograf cannot connect to Kapacitor. In the Chronograf UI I click “Configure Kapacitor” on the start page. I have the Kapacitor URL set to “[http://localhost:9092](http://localhost:9092)”, leaving username/password blank. When I click the “Connect” button I get this error message :

> Could not connect to Kapacitor. Check settings.

From the Kapacitor log;

Do I have to do anything more than installing kapacitor?

> sudo apt-get install kapacitor

Cheers
