配置 ChinaDNS 后无法 Dig 获得真实 IP

openwrt，按照 https://github.com/LazyZhu/ChinaDNS/tree/record 上的方法配置后
填好了被污染IP和国内路由表，配置好了的DNS转发，但执行dig @192.168.1.1 www.youtube.com -p5353 返回的是
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
如果执行dig @8.8.8. www.youtube.com，则返回
; <<>> DiG 9.8.3-P1 <<>> @8.8.8.8 www.youtube.com
; (1 server found)
;; global options: +cmd
;; Got answer:

但是却无法打开youtube
请教哪部分出问题了？
