I am getting a Exception 3 when I try connect to coinmarketcap.com's api using WiFiClientSecure. I tried one other library that I have that connects to a HTTPS endpoint using WiFiClientSecure and that worked, so not sure what is different between the two.

Info

Device: Wemos D1 mini
Version of core: latest (updated from master yesterday)

Sketch:

https://github.com/witnessmenow/arduino-coinmarketcap-api/blob/master/examples/ESP8266/GetTickerInfo/GetTickerInfo.ino
(you will need to install the library that this is an example of)

Last part of code of mine before the exception is:
https://github.com/witnessmenow/arduino-coinmarketcap-api/blob/master/src/CoinMarketCapApi.cpp#L15
(the serial print below this line does not get hit if its not commented out)

Some more info:
On my old windows machine that is running old core (some version of 2.3 from github) the same code works fine.

This is still an issue for me, tested today using 2.4.0-rc1

Here is a basic sketch that reproduces the error. This sketch works fine with the 2.3.0 release

Is there a special cert or something that this site uses that causes issues?

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

WiFiClientSecure client;

char ssid[] = "SSID";       // your network SSID (name)
char password[] = "pass";  // your network key

void setup() {
  Serial.begin(115200);

  // Set WiFi to station mode and disconnect from an AP if it was Previously
  // connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

  // Attempt to connect to Wifi network:
  Serial.print("Connecting Wifi: ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  IPAddress ip = WiFi.localIP();
  Serial.println(ip);

}

void connectToCoinMarket(){
  if (client.connect("api.coinmarketcap.com", 443)) {
    Serial.println(".... connected to server");
    char c;
    int ch_count=0;
    client.println("GET /v1/ticker/bitcoin HTTP/1.1");
    client.println("Host: api.coinmarketcap.com");
    client.println(F("User-Agent: arduino/1.0.0"));
    client.println();
    client.setTimeout(1200);
    char endOfHeaders[] = "\r\n\r\n";
    bool ok = client.find(endOfHeaders);

    if (!ok) {
      Serial.println("No response or invalid response!");
    }
  }
}

void loop() {
  Serial.println("Connecting To coinMarketCap");
  connectToCoinMarket();
  delay(2000);

}

Serial from above sketch:

@igrr sorry to reference you directly but would you be able to advice on the next steps with this?

It's a pretty old issue at this stage so I'm not sure if me adding a new comment would get noticed, but I am also conscious of creating a duplicate to just bump it to the top

This seems to be the same issue as reported in this comment: #3140 (comment), it was fixed in c52b0da after 2.4.0-rc1 was released. Can you try the latest git version? (installation instructions are on the front page)

Edit: looking at the backtrace again, i see that it is actually not related. Will investigate.

axtls: update to 66d530a, fixes esp8266#3335
0413d24 
SHA512 module stored padding in PROGMEM, but would then pass the pointer
to padding into Update function which would do a memcpy. Use the same
approach as with SHA256, that is to copy padding to the stack first, and
then pass it to Update.

@igrr I know you fixed this a long time ago and I forgot to get back to you and then didn't get time to test since davs reminder, but just wanted to say that i tested this out on 2.4 today and it's working fine. Thanks!
