This is a known issue with Johnny's Addon Domain functionality. It's to do with the fact the server is overloaded...the addon domain process times out half way through. Ricky and Tommy don't have this issue. Try creating the subdomain vashiyatobushtar.kapincho.heliohost.org. After that, check to see if your addon domain is listed in the addon domains screen. If it is, wait the 12 hours and clear your cache. If it does not appear, let me know and I'll escalate it for you.
