Crowdsale transaction failed

[levi0214]

I deployed to Rinkeby testnet successfully, code verify and publish is OK, Token transaction is OK, but Crowdsale transaction is always failed:

" Value transfer did not complete most likely as a result of a revert opcode."

When I deployed to local Ganache-cli，transactions also fail.

here is my solc version:
truffle version
Truffle v4.1.11 (core: 4.1.11)
Solidity v0.4.24 (solc-js)

@rstormsf I have checked the crowdsale opening time. It is valid but I still cannot send any KETH to the crowdsale contract.

Here is the crowdsale info:
