Additional Staking Failures

The first 500 AGIX are successfully transacted, but the staking of the additional 1500 AGIX fails.

  1. Enter 1500 in the staking screen
  2. Start transaction
  3. Loading takes a few minutes, but fails.
  4. It has failed more than 100 times.
    There is enough ETH in the gas money.

Can anyone help me solve this?
