I'm having trouble linking my kasa app with Google Home.
After I press Authorize from Step 7 of the instruction( http://www.tp-link.com/us/faq-1534.html), I get the error below,
401. That's an error. Your client does not have permission to the requested URL /services/auth/hadsoff/auth/complete?state=CvcV........

Anyone encountered this problem before?

I already reset my Kasa password.
Apps(Home, Kasa, Assistant, HS105 firmware) are all updated.

Thanks!
