Buy ICO Token - Buy from QR or Direct Transaction

I am not sure what kind of problem this is, but when I use the QR code on the Crowdsale page and if I do a buy function from my mobile wallet, the transaction fails. I thought that buying direct from the Crowdsale contract address would work in a ICO stage.

The url is:

aka CrowdsaleInfo address is: 0x156504bC8F49cf34E0f275b47557b739eBB0A8d7

This is on mainnet

I can’t finish my wallet and buy sell system before this is working.

any ideas?


Buy of tokens is allowed only with methodID:


Direct send to the address of crowdsale smart contract is prohibited.
