I found a very similar issue like mine. But I cannot find the answer. So I posted a new issue here. Thanks for your help! #https://github.com/ethers-io/ethers.js/issues/841#issue-621940740

Part of my code below where @uniswap/sdk used ethers.js with @ethersproject_providers @5.0.9 :

require("dotenv").config();
const Web3 = require("web3");
const {
  ChainId,
  Token,
  TokenAmount,
  WETH,
  Fetcher,
  Trade,
} = require("@uniswap/sdk");
const abis = require("./abis");
const Web3WsProvider = require("web3-providers-ws");
const options = {
  timeout: 30000, // ms
  headers: {
    authorization: "Basic username:password",
  },
  clientConfig: {
    maxReceivedFrameSize: 100000000, // bytes - default: 1MiB
    maxReceivedMessageSize: 100000000, // bytes - default: 8MiB
    keepalive: true,
    keepaliveInterval: 60000, // ms
  },

  reconnect: {
    auto: true,
    delay: 5000, // ms
    maxAttempts: 5,
    onTimeout: false,
  },
};

const ws = new Web3WsProvider(
  "wss://mainnet.infura.io/ws/v3/" + process.env.INFURA_URL_0,
  options
);
const web3 = new Web3(ws);

const {address: admin} = web3.eth.accounts.wallet.add(process.env.PRIVATE_KEY);

const init = async () => {

  await web3.eth
    .subscribe("newBlockHeaders")
    .on("data", async (block) => {
      console.log(`New block received. Block # ${block.number}`);

      const dai = new Token(
        ChainId.MAINNET,
        "0x6B175474E89094C44Da98b954EedeAC495271d0F",
        18
      );
      const weth = WETH[dai.chainId];

      const daiWeth_Pair = await Fetcher.fetchPairData(dai, weth);

      const amountsEth = await Promise.all([
        kyber.methods
          .getExpectedRate(
            addresses.tokens.dai,
            "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
            AMOUNT_DAI_WEI
          )
          .call(), //! bug possible
        daiWeth_Pair.getOutputAmount(new TokenAmount(dai, AMOUNT_DAI_WEI)),
      ]).catch(console.log);
  }).on("error", (error) => {
      console.log(error);
    });
};

init();

Just a quick parsing of these errors to help you debug it further:

Error 1: ECONNRESET while making a eth_call request to etherscan backend.

Error 2: TIMEOUT while requsting eth_blockNumber cloudfare backend.

Error 3: ECONNRESET while requesting eth_call alchemy backend.

You can read more about ECONNRESET. The backend might drop connection requests when they receive a lot of them. Also there is a possibility that your node js is trying to make a lot of connections requests but your operating system denied making any more of it.

TIMEOUT is also somewhat similar when your node js doesnt hear back from the node. It also happened with me when I was making huge amount of requests to a node. I used to get response for some of them but most of them were a TIMEOUT.

Maybe you can experiment with reducing the poling interval in your subscription.
