I’ve been having this issue very sporadically (sometimes a couple times a week, sometimes once a month). I’m curious as to how the more veteran folk here would try and narrow down the cause of this issue.
I can provide more info if needed!
Edit: More Info:
- Using a static IP (no DHCP) through Netplan.
There might still be another device on the network that is using DHCP and is getting an IP that conflicts. Do you have any visibility on the rest of the network, IP addressing, DHCP leases etc? I would check there first for a potential easy fix.
