Error: Unable to reach vacuum, handshake failed

Hi,

I have a gen2 robot and recently tried flashing it with this fork. Steps to reproduce:

mkdir -p valetudo/deployment/etc
curl https://github.com/Hypfer/Valetudo/raw/master/deployment/valetudo.conf > valetudo/deployment/valetudo.conf
curl https://github.com/Hypfer/Valetudo/raw/master/deployment/etc/hosts > valetudo/deployment/etc/hosts
curl https://github.com/Hypfer/Valetudo/raw/master/deployment/etc/rc.local > valetudo/deployment/etc/rc.local
curl --location https://github.com/rand256/valetudo/releases/download/0.4.0-RE2-fix/valetudo.tar.gz | tar --extract --to-stdout --gunzip --file=- valetudo > valetudo/valetudo
mkdir -p firmware
curl --continue-at - https://cdn.awsde0.fds.api.mi-img.com/rubys/updpkg/v11_001886.fullos.ee205b4f-7d81-45c9-95a3-a4eaeed1af52.pkg --output firmware/v11_001886.fullos.pkg

    --firmware=firmware/v11_001886.fullos.pkg \
    --public-key=$HOME/.ssh/id_rsa.pub \
    --valetudo-path=valetudo \
    --disable-firmware-updates \
    --ntpserver=192.168.178.1 \
    --replace-adbd

mirobo --debug discover --handshake true

mirobo --ip 192.168.8.1 --token xxx configure-wifi --timezone Europe/Berlin yyy zzz

I noticed that after a reboot valetudo was not running. When I ran /usr/local/bin/valetudo manually I got:

No configuration file present. Creating one at: /mnt/data/valetudo/config.json

        throw new Error("Unable to reach vacuum, handshake failed");
        ^

What could be the problem?
