Where the payment system failed. I don't understand what you mean with the payout request. Automatically the winnings were paid immediately. If a problem arise, then it should have happened at the time of withdrawal or by the time of deposit. No offense, I'm used with the site and hasn't encountered any payout issues yet.
What I mean is. I withdraw my earnings on eth about a couple of hours ago but the transaction is failed or cancelled because the wallet is out of gas.
Here is my transaction hash
0x7027cf90dab2efa50016612a3f534351a3f8d9ff0491c388f6ac9854626ad6c2
It's 0.5 ETH. I know what is the minimum withdrawal. Thank you
