first problem is solved, bitcoin-qt, leave it as it is now.
for your second problem:
bitcoin.conf
# [rpc]
# Listen for JSON-RPC connections on this port
rpcport=8332
your app credentials
public function btcReplenish(Request $request){
$bitCoinD = new BitcoinClient([
'host' => self::RDC_HOST,
[i] 'port' => 8333,[/i]
'user' => self::RDC_USER,
'password' => self::RDC_PASS,
]);
did you try to use the bitcoin-qt rpc-port:
'port' =>
8332,
