ESP 8266 Multiple Get calls on same Client? - https

Question

I'm trying to make Multiple GET calls using the same client. I've tried multiple things. New Variables, New instances. Closing Clients. The second Stock Call doesnt go through ever. It fails at "while (client.connected())" on the second Call. It Doesnt get to returning headers.
Any Ideas?
Code look like this
void loop()
{
WiFiClientSecure client;
//Stock
String payload;
// Use WiFiClientSecure class to create TLS connection
Serial.print("connecting to ");
Serial.println(host);
Serial.printf("Using fingerprint '%s'\n", fingerprint);
client.setFingerprint(fingerprint);
if (!client.connect(host, httpsPort))
{
Serial.println("connection failed");
client.stop();
//return;
}
//AAPL
String url = "/api/v1/quote?symbol=AAPL&token=XXXX";
Serial.print("requesting URL: ");
Serial.println(url);
client.print(String("GET ") + url + " HTTP/1.0\r\n" +
"Host: " + host + "\r\n" +
"User-Agent: BuildFailureDetectorESP8266\r\n" +
"Connection: close\r\n\r\n");
Serial.println("request sent");
while (client.connected())
{
String line = client.readStringUntil('\n');
// String line = client.readStringUntil('\r');
Serial.println(line);
if (line == "\r")
{
Serial.println("headers received");
payload = client.readStringUntil('\r');
//break;
}
}
Serial.println("payload");
Serial.println(payload);
// String line = client.readString();
//JsonObject& obj = doc.parseObject(payload);
StaticJsonDocument<200> doc;
DeserializationError error = deserializeJson(doc, payload);
// Test if parsing succeeds.
if (error) {
Serial.print(F("deserializeJson() failed: "));
Serial.println(error.f_str());
// return;
client.stop();
}
//{"c":23.35,"d":-0.73,"dp":-3.0316,"h":24.6986,"l":23.25,"o":24.54,"pc":24.08,"t":1627588802}
double currentprice = doc["c"];
double pctchg = doc["d"];
// Print values.
Serial.println(currentprice);
Serial.println(pctchg);
Serial.println("closing connection");
client.stop();
delay(20000);
//SPY
String spyurl = "/api/v1/quote?symbol=SPY&token=XXXX";
Serial.print("requesting URL: ");
Serial.println(spyurl);
client.print(String("GET ") + spyurl + " HTTP/1.0\r\n" +
"Host: " + host + "\r\n" +

"Connection: close\r\n\r\n");

while (client.connected())
{
String spyline = client.readStringUntil('\n');
// String line = client.readStringUntil('\r');
Serial.println(spyline);

// String line = client.readString();

Serial.println(spyerror.f_str());
// return;

Answer 1

I'm an idiot.
Needed to keep the connection open on the first call
"Connection: Keep-Alive\r\n\r\n");
