I am writing a smart contract in Truffle. Then I deploy to Rinkeby network using Mist. I follow this tutorial. But when I call methods on this contract. I meet some following things:

  • Read method: I can get return value but all is zeros value.
  • Method such as estimateGas, call (for testing method), or write method is not work.

Here is my smart contract address. As you will see some fail transactions here. But the same code successfully run on local (using local blockchain Ganache). Please tell me why.
