Trouble setup default on windows 7

[TanNguyenHuynh]

Hello, I dont know if anyone met this same issue before but I can't seem to setup the docker toolbox right at all. I am running the toolbox with windows 7 and behind a proxy, I added

export HTTP_PROXY=http://ip:port
export HTTPS_PROXY=http://ip:port
into the .bash_profile but always get stuck in the waiting for an IP line. This is the error

I have tried to remove and recreate the default machine but to no avai as well. Here is the debug log:

I'm at my wit's end. Please help. Thanks in advance.
