Home assistant core died, log

At 11:29 I have “Home Assistant stopped” in my logbook, and sure enough home assistant became unavailable then. The virtual machine was still running but unreachable by network. In the logs, I have the following. Thoughts on what’s going on? Surely this timeout fetching front door data would not bring down the server?
