  • Do you have the exact error message? Also make sure the sender account has enough balance to deploy the contract.

  • I have checked account balance and it is 0. will it be the primary reason for this error? Jan 25, 2018 at 8:48
  • If that is the reason behind this error then how can i able to update account with some balance? Jan 25, 2018 at 8:56

  • Make sure you are connecting to your private network, and unlock your account.
