Using ethers, invalid cors

Moralis General
#1

I want to use ethers for calling functions
in the instructions I saw I need the NODE_URL I presume the meaning is speedy nodes and not server_node ( I tried both).

this is what I am seeing

this is my code

import { ethers } from "ethers";
......
 const ethers = Moralis.web3Library;

 const NODE_URL =
    "https://speedy-nodes-nyc.moralis.io/xxxxxx/bsc/testnet";
  const provider = new ethers.providers.JsonRpcProvider(NODE_URL);

  async function info() {
    const signer = provider.getSigner();
    const contractAddress = "0x21daB594d4726d1e12fAD9b5aE7EE270C07F6b75";
    const contract = new ethers.Contract(contractAddress, abi, provider);
.....
}

how can I overcome the issue?

#2

you can get that error also when that url is not accessible, it can happen when you have VPN for example

#3

vpn is off the issue is still on
what can I do?
NODE_URL is speedy node link?

#4

the node url seems fine, yes, it is the speedy node link

#5

the problem is the provider
do you think that is happening due to the fact that I am calling to the speedy nodes, and server url?
