Same error number as here: https://xenforo.com/community/threa...ing-timed-out-after-3000-milliseconds.181776/


Or maybe it's related to @Xon's add-on mentioned in the server error log.

Alert Improvements doesn't actually influence the number of alerts being dispatched. This is likely some sort of throttling, or just generic network issues being applied to your server from the end-point it is trying to push to
