Unable to unlock coinbase account

### Issue Details

After deploying the Ethereum consortium Leader Blockchain, I am trying to SSH in the first TX node. After successfully accessing the the VM of the TX node, I try to unlock the account using

"personal.unlockAccount(eth.coinbase)"

However, I get this error "Error: could not decrypt key with given passphrase".

I used the same passphrase/password, that I entered before deploying the Ethereum Consortium

The issue names no repository file, test, or entry point; begin by locating the Ethereum consortium deployment template and its account or passphrase documentation. Reproduce the unlock command against a deployed TX node, then establish a confirmed cause and resolution before considering any code change.
