I can not call a function dynamically

token.methods.balanceOf(accounts[0]).call().then(result=>{
    console.log(result);
   $creditsValue.innerHTML = result;
});

In this code when I try to fetch the balance from the contract dynamically it does not work and returns 0.
But when I check the balance manually it works like this:

token.methods.balanceOf('0xC9bb53aBc2DAA3726D6D2FD38B2664F2889EBb0d').call().then(result=>{
console.log(result);
$creditsValue.innerHTML = result;
});

Although the dynamic expression works fine in local network, but this problem is arising on the test network
Can someone please tell what’s the problem it is urgent
