Console can't ping any after installed shadowsocks-libev with luci-app

console can't use net like ping or opkg update
but Network/Diagnostics can use ping , and can ping out

after disenable ShadowSocks-libev setting , still not working any at console , but computer at LAN can use net

I checked routes and firewall ,
and i use pure img install ,then only opkg install shadowsocks-libev with luci-app , but still not work

some changed after that , but i can't know where why
