JSON RPC API call from webpage

Hello, I want to make API calls to my Bitcoin Core wallet from my webpage but when I try to connect it gives me Internal Server Error

I'm using easybitcoin.php JSON from https://github.com/aceat64/EasyBitcoin-PHP

I'm trying with this JSON RPC call:

Code:

require_once('easybitcoin.php');
$bitcoin = new Bitcoin('myusername','mypassword','myip','8332');
$bitcoin->getinfo();
?>

My bitcoin.conf file has:

Code:

listen=1
maxconnections=15
server=1
daemon=1
rpcuser=myusername
rpcpassword=mypassword
rpcclienttimeout=60
rpcport=8332
rpcallowip=0.0.0.0/0 (Before I put my IP address here but it didn't solve too)

When I use bitcoin-cli.exe client to send commands to my Bitcoin Core server via 127.0.0.1 (localhost) it works perfectly.

What I'm doing wrong?
