I performed an upgrade of a 6.15.1 instance of confluence to 7.0.1. All seems to be working fine. Every single page I try to export to PDF just hangs. No progress indicator or any other indication of anything going on except for the browser stating "waiting for...". This goes on for 300 seconds, untill the nginx server that fronts confluence times out and throws an error.
Log available here: https://pastebin.com/dfMMp6e0
I've been trying everything but I still cannot figure this out.
