I got this problem since yesterday and it never succeeded. I tried to investigate the transaction on etherscan and it said "Sorry, We are unable to locate this TxnHash" URL => https://rinkeby.etherscan.io/tx/0x383b3220d647c2633c5b667e8093e2fe66bb605b2b462120eabbf38a9175dd40
I cannot cancel the transaction also. I can no longer use this account anymore.
How can I fix this problem?
