    Starting etcd v3.4, etcd wouldn't serve API v2 by default. You'll need to add --enable-v2=true in your etcd startup script to enable API v2.

    In your guide's case, add it on step 3 in ExecStart when creating your etcd.service systemd unit file, i.e.

    ExecStart=/usr/local/bin/etcd \\
  --name ${ETCD_NAME} \\
  --enable-v2=true \\
  --data-dir=/var/lib/etcd \\
