The contract interface for web3 deployment always fails, and the local call is successful.

my contract:

https://kovan.etherscan.io/ad.

I try to use web3 to adjust the interface in the contract, for example: 

  https://remix.ethereum.org/-sharpo.


 I have tried other nodes with infura and failed. I use chrome with MetaMask extension, web3@ ^ 1.0.0-beta.33.
