I've noticed when I close particularly large runs/plans, it can take a long time for the server to respond. Unfortunately, our proxy returns a 502 error if there is no server response in <30 seconds.
Ultimately the closing always continues and finishes up fine. But it is not a great experience to have an unresponsive UI for such a long time.
Would it be possible to instead close the run/plan in the background and give a server response immediately? You already do this for other long-running processes such as Reports.
Thanks!
