You’re creating a PDF that spans a large amount of data and Kibana is hitting this xpack.reporting.queue.timeout, I would try generating the PDF with less data to check if that's the issue, before updating the timeout value.
Kibana is hosted behind a reverse-proxy, and the Kibana server settings are not configured correctly.
