Moralis V1 walletconnect login doesn't work

Hi, Iā€™m using this code for the user login:

import { useMoralis } from 'react-moralis';
import { useEffect, useState } from "react";
import Moralis from 'moralis-v1';

// import metamask from '/images/metamask.png';

export const LoginComponent = ({ closeModal }) => {
  const { isAuthenticated, authenticate, enableWeb3, account, chainId } = useMoralis();
  const [authError, setAuthError] = useState(null);
  const [isAuthenticating, setIsAuthenticating] = useState(false);
  
  const handleAuth = async (provider) => {
    try {
      await Moralis.start({
        apiKey: process.env.NEXT_PUBLIC_MORALIS_API_KEY,
        serverUrl: process.env.NEXT_PUBLIC_MORALIS_SERVER_URL,
        appId: process.env.NEXT_PUBLIC_MORALIS_APP_ID
      });


      setAuthError(null);
      setIsAuthenticating(true);

      // Enable web3 to get user address and chain
      await enableWeb3({ throwOnError: true, provider });


      // console.log(account, chainId, provider)

      if (!account) {
        throw new Error('Connecting to chain failed, as no connected account was found');
      }
      if (!chainId) {
        throw new Error('Connecting to chain failed, as no connected chain was found');
      }

      // Get message to sign from the auth api
      const { message } = await Moralis.Cloud.run('requestMessage', {
        address: account,
        chain: chainId,
        network: 'evm',
      });

      // Authenticate and login via parse
      await authenticate({
        signingMessage: message,
        provider: provider,
        chainId: chainId,
        throwOnError: true,
      });
      
    } catch (error) {
      console.log(error)
      setAuthError(error);
    } finally {
      setIsAuthenticating(false);
    }
  };

  const buttonStyle =
    "bg-black backdrop-filter animate-fade-in-up py-2 px-6 mt-4 text-white text-base font-bold rounded-2xl border-black border-2 border-b-8 transform duration-300 hover:scale-1002 hover:shadow-bluxl";

  useEffect(() => {
    if (isAuthenticated) {
      closeModal()
    }
  }, [closeModal, isAuthenticated])

  return (
    <div className='w-full text-center py-12 grid px-8'>
      <button className={buttonStyle}
        onClick={() => {
          handleAuth("metamask");
        }}>
        {/* <metamask className='w-6 h-6 inline-block mr-2' /> */}
        Metamask
      </button>
      <button className={buttonStyle} onClick={() => handleAuth("walletconnect")}>
        Walletconnect</button>
        <div className='pt-6 text-center text-xs animate-pulse font-bold'>{isAuthenticating ? "Authenticating..." : ""}</div>

    </div>
  )
}

walletconnect is not working, both on desktop browser and mobile, the console errors are the following:

POST https://speedy-nodes-nyc.moralis.io/WalletConnect/polygon/mumbai net::ERR_FAILED

Error: PollingBlockTracker - encountered an error while attempting to update latest block:
undefined

Any suggestion on how we could fix this?
