After I restart I can't ever pull up the web interface. My server is headless, so have had to attach a monitor, log in to the CLI and run 'dhclient'.
Before that command "ip addr" shows the default local IP.
As soon as I manually run this dhclient command, the webgui loads instantly.
This wasn't the case until I moved the server into another room, attached to another switch (layer 2, un-managed). At that time, I also removed a graphics card and sound card. I've got to assume those are totally unrelated.
This seems weird. Any ideas?
