Hello, I ma trying to communicate my NODEMCU ESP32 to Ethereum network through infura. However, I got an error when starting connection to server. The image below show the error:

this is my code: `#include

include

define ENV_SSID "dlink"

define ENV_WIFI_KEY ""

define INFURA_HOST "mainnet.infura.io"

define INFURA_PATH "ee31c1d4946c4dbb89debb7d4af08cf3"

Web3 web3((string)INFURA_HOST, (string)INFURA_PATH);

void setup() { Serial.begin(115200); for(uint8_t t = 4; t > 0; t--) { Serial.printf("[SETUP] WAIT %d...\n", t); Serial.flush(); delay(1000); } WiFi.begin(ENV_SSID, ENV_WIFI_KEY); // attempt to connect to Wifi network: while (WiFi.status() != WL_CONNECTED) { Serial.print("."); // wait 1 second for re-trying delay(1000); } Serial.println("Connected"); string result = web3.Web3ClientVersion(); }

void loop() { // put your main code here, to run repeatedly: }`

string INFURA_HOST = new string("mainnet.infura.io"); string INFURA_PATH = new string("/");
