Hi Tyler,
I can provide the file, but I don’t think that’s the issue, as this seems to happen for any file that’s fetched after the server has been online for some time.
Do clients need to unsubscribe from using the server? Is there something else that would explain why the heartbeat calls would fail?
This seems to be indicative of an overall server failure as it is also experiencing other issues around the same time (WebViewer Server timeouts - #6 by kkim)
