If you have Luci installed and you hit /cgi-bin/luci/admin/network/diagnostics the default field values are dev.openwrt.org. Since the OpenWrt infrastructure is known to have gown down in the past, I suggest those are replaced with lede-project names or something else stable and world-wide accessible.
