Disable verification of certification SSL A7670SA

Question

I have the code below and it doesn't work with my URL. I receive a

715(Handshake Failed)

This code below works normally, but with my API it doesn't work.

I'm using a A7670SA with Arduino Mega 2560.

My API is on Heroku and uses an Automated Certificate Management by Heroku, that uses the Let's Encrypt.

String sendATCommand(String command, String expectedResponse = "", unsigned long timeout = 5000) {
 Serial1.println(command);
 Serial.println("Command send: " + command);
 unsigned long startTime = millis();
 String response = "";
 while (millis() - startTime < timeout) {
 if (Serial1.available() > 0) {
 char c = Serial1.read();
 response += c;
 }
 }
 response.replace(command, "");
 Serial.println(response);
 delay(500);
 return response;
}
void setup() {
 Serial.begin(115200);
 while (!Serial)
 ;
 delay(1000);
 Serial1.begin(115200);
 sendATCommand("AT", "OK"); 
 sendATCommand("AT+CGREG?");
 sendATCommand("AT+CGDCONT=1,\"IP\",\"claro.com.br\"", "OK");
 sendATCommand("AT+HTTPINIT"); // Iniciar ambiente HTTP
 sendATCommand("AT+HTTPPARA=\"URL\",\"https://httpbin.org/\"");
 sendATCommand("AT+HTTPACTION=0", "OK", 1000);
 sendATCommand("AT+HTTPREAD?");
 sendATCommand("AT+HTTPTERM", "OK");
}
void loop() {}
