Description

Hi, I use the latest 2.02 arduino core but I have an issue with the https connect. It work well one-two time, after the connection failed.
If I use the 2.01 version all work well.
The debug show connection failed with -1 error

I tried various option (PSRAM, no PSRAM), and various code configuration but the issue still happaning. My only solution is to downgrade to 2.01. I don't tried the 2.00.

Sketch

WiFiClientSecure client;

  client.setInsecure();

  if(client.connect(server, 443)) {
    client.setTimeout(30);
    TelnetStream.println("Connected to server");
    client.println("POST /api/measurements HTTP/1.0");
    client.println("Host: *******");
    client.println("Authorization: Bearer " + String(token));
    client.println("Content-length: " + String(parameters.length()));
    client.println("Connection: Close");
    client.println("Content-Type: application/json;");
    client.println();
    client.println(parameters);
    client.stop();
  }

I can confirm the same problem on ESP32-C3.
A WiFiClientSecure object cannot be used after closing a connection. This breaks several libraries depending on it.

The problem is caused by f29f448 and the changes introduced in lines:

arduino-esp32/libraries/WiFiClientSecure/src/ssl_client.cpp

Line 49 in f29f448

memset(ssl_client, 0, sizeof(sslclient_context));

arduino-esp32/libraries/WiFiClientSecure/src/ssl_client.cpp

Line 331 in f29f448

memset(ssl_client, 0, sizeof(sslclient_context));

This not only resets all pointers (as intended) but it also sets all other fields in the struct to 0, including handshake_timeout. This in turn never has a chance to complete it in

arduino-esp32/libraries/WiFiClientSecure/src/ssl_client.cpp

Line 265 in f29f448

if((millis()-handshake_start_time)>ssl_client->handshake_timeout)

Hello, can you please retest this on v2.0.3-rc1?

I'm closing the issue as expired due to no answer.

If needed, please reopen it.

Thanks for understanding.
