@NolanHerring is there at least 1Mbps of bandwidth, similar to the rule-of-thumb requirement when using MV Cloud Archive? I've heard of a known issue where insufficient bandwidth can cause the export to fail before completion. It's being looked into, I don't have a status. If you're viewing video already, then I would not expect any firewall issue to be the cause, because the export is going to happen over the same TLS/SSL connection as your video when viewing via the cloud proxy, so I'd assume you've already got TCP/30001 open and working, so that's not related to exports failing. My only guess might be limited bandwidth, but perhaps open a case, to confirm or deny you're hitting a known issue and if so perhaps get a timeframe update.
