HTTP_UNAUTHORIZED , Problem #18463

Unfortunately I'm using Linux, and bitcoin.conf is not maked auto ! so i make a file in the "/root/.bitcoin" path with this content:

prune=600
maxconnections=12
maxuploadtarget=20
rpcuser=user
rpcpassword=user
daemon=1
keypool=10000

So tell me why i cant connect to rpc json and i get following error : HTTP_UNAUTHORIZED

when i remove rpc user and rpc password, then in "terminal" everything is work, but when i set credential, i get following error: Authorization failed: Incorrect rpcuser or rpcpassword

so this code not work: bitocin-cli -rpcuser user -rpcpassword user getnewaddress or bitocin-cli -rpcuser=user -rpcpassword=user getnewaddress

my user is: "user" and password is "user". but why not work ?

why bitcoin have bug ?

this is very simple things. why this not work ?

php code not work:

$bitcoin = new Bitcoin('user','user', '127.0.0.1', '8332');

$info = $bitcoin->getBalance();

var_dump($info); // FALSE
var_dump($bitcoin); //HTTP_UNAUTHORIZED

nodejs code not work:

var bitcoin = require('bitcoin');

var client = new bitcoin.Client({
    host: '127.0.0.1',
    port: '8332',
    user: 'user',
    oass: 'user',
    ssl: false,
    sslStrict: false
});

client.getWalletInfo(function (err, result) {
        if (err) {
            res.send(err.message); // 401 status
        }
        else {
            res.send(result);
        }
    });

just worked in terminal without creditnal.

how can fix this.

After restart bitcoind, now is worked ! thanks.

now problem after problem in the next steps. in the twenty first century, provide the tools in a way that does not require for enter commands. The Linux system has really ruined everything.
