Can't visit some websites via socket proxy, by BitVise

I have a machine A, which can't visit YouTube. Another machine B is an Azure virtual machine, which can of course visit YouTube.

I set up BitVise in machine B and SSH to B from A with allowing port forwarding -D 8888.

Currently I still could not visit YouTube in A. BitVise reports the error below:
