Kapacitor and Proxy servers

Hi, is it possible to configure Kapacitor to send data via a proxy server?

My current set up:

I have local TICK stack installations at customer sites, from there I use Kapacitor to stream data to an Influx instance in our DC so we can alert from there.

One customer has a proxy in place, I’ve configured my server to use this proxy however Kapacitor data never seems to reach the proxy. It looks like it is trying to go straight out through the internet instead.

As a test, we added a rule to the firewall to simply allow the traffic, which is now working. But ideally i would like to put Kapacitor behind this proxy.

Can this be done?
