@parachutesj I am very well aware of that. But what I'm asking here is how to do this from MyNodes.net? Sorry for not making that clear. If that can't be done is there any other controller that would support this?

I already tried that. I tried it again. Then I tried some more and figured it is some problem with power supply which prevents it to work when communicating with node that requires signing. It seems to work now. Thanks for your help.
