Hi,
I've verified with the attached code that when a SSL handshake error occurs, a memory leak is generated
Moreover espconn_reconnect_callback is not called signaling ESPCONN_HANDSHAKE - TCP SSL handshake fails.
The code try to connect to a server every 10 seconds and every time SSL fails heap decrease of about 1952 bytes

The heap size in the output is printed by a timer in the user_main.
Have you ave any ideas?
Thanks
Regards

Sergio
