Arduino IDE (visual micro) ESP32-wrover

Hi,

I am new to this library and I having some memory issue when the connection is failed. it's not clear to me where the leak is coming from. I have updated the ssl_client library where memorie leak is detected in dec 2021, but still having a leak somewhere...
