Prometheus-node-exporter-lua refuses to start (defering start until listen interface becomes ready)

Installing and Using OpenWrt

I am trying make prometheus-node-exporter-lua bind to

config interface 'ANT'
        option proto 'none'
        option device 'tinc_ant'
        option defaultroute '0'
        option peerdns '0'

which is opewnwrt interface over tinc manged linux interface:

11: tinc_ant: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN qlen 500
    link/[65534]

But having /etc/config/prometheus-node-exporter-lua
option listen_interface 'ANT' # NOTE: must be OpenWRT iface
still fails:
prometheus-node-exporter-lua: defering start until listen interface ANT becomes ready

Seems only
option listen_interface '*'
works, and prometheus-node-exporter-lua start.

TIA for any hints.
