Hello comunity! I’ve been using Blynk for a while with a wemos d1 mini as a WI-FI shield (esp12f) with an arduino nano and bellow code as base, today the “system” stoped working, when I load another code without ssl directly to the wemos it keeps disconecting too, it seems that the blynk cloud disconnect the board, only works when I use the ssl example code, but I need to use the board as a shield, and it doesn’t offer the ssl code for this setup, thanks for any help and sorry for my bad english…
Download latest Blynk library here:

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

WARNING!
It's very tricky to get it working. Please read this article:
http://help.blynk.cc/hardware-and-libraries/arduino/esp8266-with-at-firmware
This example shows how to synchronize Button widget
and physical button state.
App project setup:
Button widget attached to V2 (Switch mode)
