Sorry to necro this thread… but today we had this very issue in our environment.
Someone by mistake, deleted a bunch of files from the wwwrootbes/uploads folder.
Problem is, some relay have the files in their caches, but some do not, so some client now and then requests a download that will never complete.
Looking at the action in the console, the download status correctly shows:
Download error: “Unexpected HTTP response: 404 Not Found”
I know I can take a look at the failed downloads in the Relay Diagnostics, but… is there a session relevance to find out which actions are failing to download?
I mean, is not the action status, as the action is open, but there’s no action download status that I know of…
