Ethereum Error: authentication needed: password or unlock

Question

0|server | (node:99208) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 53): Error: authentication needed: password or unlock

This is happening randomly, sometimes the api call pass through successfully, and sometimes nodejs app logs show this. I unlocked the account multiple times using multiple ways giving me "true" boulean as follows:

personal.unlockAccount(eth.coinbase, "cDxxxxxxxxKaYZ", 300)

geth --exec "personal.unlockAccount(eth.accounts[0], 'cDb xxxxxxxKaYZ', 1000)" attach

it keep on randomly showing the same error authentican needed with no clue!

PS I am using azure ethereum consortium network with Geth and MetaMask

我发现了。这是负载平衡服务器中的一个问题，因为我的体系结构由多个服务器组成。这就是为什么某些请求成功而其他请求却不成功的原因！
