Listening stops when OS goes on sleep

[aduninon]

Describe the bug
I am running the piece of code below to listen to created pairs but I noticed that when my OS goes on sleep and that I turn it on again it stops listening. is that normal ? If yes, would please explain why ?
Reproduction steps

new Ethers.Contract(
    addresses.factory,
    [
        'function getPair(address tokenA, address tokenB) external view returns (address pair)',
        'event PairCreated(address indexed token0, address indexed token1, address pair, uint)'
    ],
    account
).on('PairCreated', async (token0, token1, pairAddress, uint) => {
        logger.info(`
        New pair detected - #${uint}
        =================
        token0: ${token0}
        token1: ${token1}
        pairAddress: ${pairAddress}
      `);
    });

Environment:
MacOS

Are you using a WebSocket? When the socket disconnects, there is no way for ethers to re-establish that connection, as it was managed by the OS.

In v6, you can pass in a function that creates a WebSocket, which can be re-called on closure to continue events.
