How to connect to ETHW network?

[Bug-terminator]

Hi, frens. I'm using ether.js to connect ETHW network:

const ETHF = 'https://rpc.etherfair.org/';
const ETHW = 'https://mainnet.ethereumpow.org';
const provider = new ethers.providers.JsonRpcProvider(ETHW)

however, I got following issue:
node:1632) UnhandledPromiseRejectionWarning: Error: could not detect network(event="noNetwork", code=NETWORK_ERROR, version=providers/5.7.2)
but ETHF works good for me, could you please tell what's wrong with it?

This usually means the URL is incorrect.

It would also occur if the eth_chainId RPC wasn’t working correctly, which may be the case as I don’t know what type of support ETHW has.

Ser, can you recap this problem on your PC? The URL is the same as the one in metamask, so it couldn't be wrong.
