Thanks for the logs.
You are running the server on wifi. That is not recommended.
What I can see is that there was no active working network interface on your last server launch at 20:17 on Apr 10, 2019
So it appears that the network card died and was not operational when you relaunched the server
This shows all outgoing requests failing - no DNS

The area to look into the network card and i would recommend switching to an ethernet cable connection and not rely on wifi
