Error 500 when trying to deploy

[wowgitwow]

Hi,

I have forked the repo and changed just the mnemonic phrase from mytonwallet web, but whenever I try to deploy it just fails each time, many times with error 500 , sometimes show connection timedout, while throwing the error it also provides the data being posted (BOC), which i have tried with other API's as well which then throws the following error when trying to send through toncenter's api v2 endpoint for send boc : LITE_SERVER_UNKNOWN: cannot apply external message to current state : Failed to unpack account state.TON Blockchain.

One reason could be wrong address being generated? I see the address for which it shows TON balance and prints is different to my address which shows up in the wallet, but the mnemonics are correct
Can anyone help in resolving this issue?
