I'm getting this error when I'm trying to run truffle migrate --network mainnet --reset

 * Use this file to configure your truffle project. It's seeded with some
 * common settings for different networks and features like migrations,
 * compilation, and testing. Uncomment the ones you need or modify
 * them to suit your project as necessary.

 * Hands-off deployment with Infura
 * --------------------------------
 *
 * Do you have a complex application that requires lots of transactions to deploy?
 * Use this appproach to make deployment a breeze 🏖️:
 *
 * Infura deployment needs a wallet provider (like @truffle/hdwallet-provider)
 * to sign transactions before they're sent to a remote public node. 
 * Infura accounts are available for free at 🔍: https://infura.io/register
 *
 * You'll need a mnemonic - the twelve word phrase the wallet uses to generate
 * public/private key pairs. You can store your secrets 🤐 in a .env file. 
 * In your project root, run `$ npm install dotenv`. 
 * Create .env (which should be .gitignored) and declare your MNEMONIC 
 * and Infura PROJECT_ID variables inside.
 * For example, your .env file will have the following structure:
 * 
 * MNEMONIC = <Your 12 phrase mnemonic>
 * PROJECT_ID = <Your Infura project id>
 * 
 * Deployment with Truffle Dashboard (Recommended for best security practice)
 * --------------------------------------------------------------------------
 * 
 * Are you concerned about security and minimizing rekt status 🤔?
 * Use this method for best security:
 * 
 * Truffle Dashboard lets you review transactions in detail, and leverages 
 * MetaMask for signing, so there's no need to copy-paste your mnemonic. 
 * More details can be found at 🔎: 
 * 
 * https://trufflesuite.com/docs/truffle/getting-started/using-the-truffle-dashboard/

I've been looking around the web and haven't found anything that can help me out. Would be appreciate it if someone can help me out here

Hi,
you have, in your truffle_config:
mainnet: {
provider: () => new HDWalletProvider(
process.env.PRIVATE_KEY,
process.env.INFURA_URL
),
network_id: 1, // mainnet
}
I can't see why the network you are connected to would return a network ID of 15445072, though I can't see the value of your INFURA_URL.

My mainnet network is configured thusly:
mainnet: {
provider: () =>
new HDWalletProvider({
privateKeys: [process.env.private_key],
providerOrUrl: https://mainnet.infura.io/v3/${process.env.PROJECT_ID},
}),
network_id: "1",
},

I suggest you look at your URL carefully. NOTE that you are using the legacy deprecated method of specifying HDWalletProvider options. Suggest you switch to the new method, see:
https://github.com/trufflesuite/truffle/blob/develop/packages/hdwallet-provider/README.md#instantiation

I hope this helps, do please update us with how you go.

Warm regards,
Chris | Infura | ConsenSys

Hi @cipaterson
Thanks for your response. Here's my INFURA_URL, which is retrieved from environment variable .env

INFURA_URL=wss://mainnet.infura.io/ws/v3/<infura_key>

I'm using the websocket version
