Failed to send request: Operation not permitted

[lbkustb]

The 'Failed to send request: Operation not permitted' was spit out after I use the 'my_ip=$(wget -6 -qO - 'http://[2001:da8:208:100::115]:80/get_ip.php' | sed "s/^gIpV6Addr = '//g" | sed "s/';//g
" | sed "s/\r//g" | sed "s/\n//g")' command.
Based on an openwrt based on mt7621.

Make sure the ipv6 network on your router is working, then try running wget -qO - http://cippv6.ustb.edu.cn/get_ip.php or curl http://cippv6.ustb.edu.cn/get_ip.php from the router command line to check if the ipv6 address is returned properly.
