Unable to generate PNG or PDF reports

[e100]

When trying to download a PDF or PNG report I get the message "Error downloading report"

Error logs from kibana:

I have kibana setup to listen using TLS, connecting to it as http would result in an ERR_EMPTY_RESPONSE exception.

Perhaps the hard coded LOCAL_HOST constant is the source of the problem?
