Help- Multiple instances

[michaeloconnor1717]

I am attempting to make a smart clock that gets information from two different servers (Google scripts and api.weather.gov). I wanted to know if that is possible because I have been unsuccessful so far. I can connect to them separately, but when I try to connect to both of them in the same script it drops the connection to the first one and fails to connect to the second one.

Sketch

TTPSRedirect* google = nullptr;
const char* host = "script.google.com";
const int httpsPort = 443;
const char* fingerprint = "";
String url = String("/macros/s/") + GScriptId + "/exec";

HTTPSRedirect* weather = nullptr;
const char* host1 = "api.weather.gov";
String url1 = "/gridpoints/LZK/49,94/forecast";

SoftwareSerial espToMega(16, 5);

// Define NTP Client to get time
#define utcOffsetInSeconds -18000
WiFiUDP ntpUDP;

NTPClient timeClient(ntpUDP, "pool.ntp.org", utcOffsetInSeconds);
void setup() {
  pinMode(10, INPUT);
  espToMega.begin(115200);
  Serial.begin(9600);
  delay(10);
  Serial.println('\n');

  // Connect to WiFi
  WiFi.begin(ssid, password);
  Serial.print("Connecting to ");
  Serial.print(ssid); Serial.println(" ...");

  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.print(".");
  }

  Serial.println('\n');
  Serial.println("Connection established!");
  Serial.print("IP address:\t");
  Serial.println(WiFi.localIP());

  // Use HTTPSRedirect class to create a new TLS connection
  google = new HTTPSRedirect(httpsPort);
  google->setInsecure();
  google->setPrintResponseBody(true);
  google->setContentTypeHeader("application/json");

  espToMega.println("Connecting");
  Serial.print("Connecting to ");
  Serial.println(host);

  // Try to connect for a maximum of 5 times
  bool flag = false;
  for (int i = 0; i < 5; i++) {
    int retval = google->connect(host, httpsPort);
    if (retval == 1) {
      flag = true;
      Serial.println("Connected");
      break;
    }
    else
      Serial.println("Connection failed. Retrying...");
  }

  if (!flag) {
    Serial.print("Could not connect to server: ");
    Serial.println(host);
    return;
  }

  weather = new HTTPSRedirect(httpsPort);
  weather->setInsecure();
  weather->setPrintResponseBody(true);
  weather->setContentTypeHeader("application/json");

  espToMega.println("Connecting");
  Serial.print("Connecting to ");
  Serial.println(host1);

  bool flag1 = false;
  for (int i = 0; i < 5; i++) {
    int retval1 = weather->connect(host1, httpsPort);
    if (retval1 == 1) {
      flag1 = true;
      Serial.println("Connected");
      break;
    }
    else
      Serial.println("Connection failed. Retrying...");
  }

  if (!flag1) {
    Serial.print("Could not connect to server: ");
    Serial.println(host1);
    return;
  }

  espToMega.println("clear");
  espToMega.flush();
  delay(500);
  // delete HTTPSRedirect object
  delete google;
  google = nullptr;

  delete weather;
  weather = nullptr;

  timeClient.begin();
  timeClient.update();
  getInitialTime();
  delay(1000);
  requestEvents();
}

Welcome to HTTPSRedirect! Please provide enough info to debug the issue.

esp8266 does not appear to have the capabilities to handle multiple connections simultaneously, but closing one and opening another (so just switching back and forth) works like a charm
