Failed to connect to myip.ipip.net port 80:Connection refused

Hello! I have a problem without solutions. If you can see it, could you give me some advice?
I try to set my output tcp netflow to redsocks, the code is :
sudo iptables -t nat -A OUTPUT -p tcp -j REDSOCKS
then I try to use curl, but it becomes
xxx@xxx-VirtualBox:~$ curl myip.ipip.net --ipv4 curl: (7) Failed to connect to myip.ipip.net port 80: Connection denied
Before I typed, I have set these rules:
`xxx@xxx-VirtualBox:~$ sudo iptables -t nat -N REDSOCKS

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d jp6mk2.jp.cloudnode.bid -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 0.0.0.0/8 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 10.0.0.0/8 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 127.0.0.0/8 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 169.254.0.0/16 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 172.16.0.0/12 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 192.168.0.0/16 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 224.0.0.0/4 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -d 240.0.0.0/4 -j RETURN

xxx@xxx-VirtualBox:~$ sudo iptables -t nat -A REDSOCKS -p tcp -j REDIRECT --to-ports 12345`

and the curl is noral.
Now I dont know how to solve it, do you have any good advice?
