Blynk library version: 0.6.1 IDE: PlatformIO IDE version: [...] Board type: ESP8266 (Wemos d1 mini)

Scenario, steps to reproduce

I am trying to connect a ESP8266 to my own Blynkserver via SSL. The port is 19443. Blynk.config("token", "10.1.2.3", 19443);

Expected Result

The controller should connect.

Actual Result

The connection fails with SSL error 56. Without SSL everything works as expected.

Please disable SSL, and re-flash your device. Unfortunately this is going to be the only cure for this issue. More details in this comment: https://community.blynk.cc/t/esp8266-ssl-connections-down-using-blynk-wifimanager-esp32-works-fine-non-ssl-8266-works-fine/52144/5?u=vshymanskyy
