error: [ServiceEndpoint]: Error: Failed to connect before the deadline on Endorser- name: peer2-org0

Question

Help me please! I ran my hyperledger fabric network with:

1. org0

• orderer1-org0
• peer1-org0
• peer2-org0

2. org1

• peer1-org1
• peer2-org1

3. org2

• peer1-org2
• peer2-org2

My Node.js app:

async function getClientID(label) {
    let wallet = await Wallets.newCouchDBWallet("http://XXXX:5984");
    let user = await wallet.get(label);

    // connection profile
    let connectionProfile = yaml.safeLoad(readFileSync('path/to/config.yaml', 'utf-8'));
    // create new gateway
    let gateway = new Gateway();
    await gateway.connect(connectionProfile, {
        wallet,
        identity: label,
        gatewayDiscovery: { enabled: true, asLocalhost: true }
    });

    // get the network (channel) our contract is deployed to
    let network = await gateway.getNetwork('mychannel');

    if (network) {
        let tokenERC20Contract = network.getContract('token-erc-20');
        let clientID = await tokenERC20Contract.evaluateTransaction('ClientAccountID');
        console.log(`clientID for ${label}: `, clientID.toString('ascii'));
    }
}

I register some users and put their identities into the couchdb wallet successfully. Now I want to get client id from my network. I get this id successfully, but before I receive many error logs:
