I see that there is some routing or vpn connection being made - so unsure how this is configured on a fresh install? Or is this from a hard power off?
What do the logs show on the second boot?
I'm unsure what you mean with VPN connection. I don't use VPN on my LibreELEC client.
I just configured WIFI with SSID and password. Client will get an IP from DHCP server via reservation.
How can I access the logs without CLI (e.g. via GUI) on second boot? Because of missing network connection I'm not able to connect to client via ssh. The log that I see in GUI has a lot less information than I got via ssh.
