Sadly we were not able to pinpoint the cause of the issue. Only thing I can intuitively point to is that we were hosting ERPNext on a local network.
For future posters on this thread, including you @kptdaaron, please mention your hosting/network as well, and whether there’s something unusual about it.
Overtime a trend should appear and bring us closer to the issue. I’d also like to look at the logs in bench/sites/<site-name>/logs
