The "no_routes" error means that WhatsApp Inc. doesn't have a way to make a call to your country. So you can only register via SMS. You already tried too many times and have to wait about 12 hours to try again. What you can do is BEFORE trying again use the link in this Leinad post to request a code. AFTER you get the code in your phone, write it down and start Yappari registration. Wait for it to fail and then type the code when Yappari asks you for it and that's it.
