Trouble unlocking bootloader htc one M8 hk

[AC Question]

I was attempting to unlock the bootloader on my HTC one M8 Hk. Went to the HTC Dev site and was following the instructions and when I got to the command line part to get the unlock token my phone wasn't showing up or I guess it wasn't communicating with my computer. I have android studio installed and all the other software up to date. Any suggestions?
