What was the last thing or most recent thing you did? Did you undo it?
Did you hook this to anything else? If not why not?
Did you try different cables?
Things to do after initial install:
Fix date timedatectl set-timezone America/Los_Angeles
Update Pi-KVM, follow #news on Discord for instructions
pacman -S avahi nss-mdns gtk3 python-dbus python-gobject
Enable the Avahi daemon in order to make it persistent after reboot:
systemctl enable avahi-daemon.service
Start the DBus (if not already running) & Avahi daemons:
systemctl start dbus.service
systemctl start avahi-daemon.service

Troubleshooting
It is expected that you are aware of basic networking while working on this project and that you have read up on the project prior to going to Discord
Do you know the IP?
Can you ping the IP?
Did you swap cables?
Did you swap the eth port to a known working eth port?
Do you have access to another router or switch?
Did you change ports on the router/switch?
RPi4 - Did you hook up a monitor? Once logged in, can you ping to your gateway? Other IP's on the same network?
Did you connect a monitor to the target? Does it work?
Did you connect the PIKVM to the target directly? Does it work?
