Hi @eric2, did you tried the current version from master? It solves some problem related with SSL, as we told here:

Connection Issues regarding ESP8266/Node MCU devices

Since ESP8266 2.5.0 core version, the default TLS/SSL client was replaced in the given libraries, as the replaced the axTLS by BearSSL. This was causing all new flashed devices to prevent the default communication over TLS/SSL, as this library requires now to specify an SSL fingerprint, o explicitly mark the connection as insecure (accept any given server certificate), over setInsecure or setFingerprint methods. So, the only solution was to disable the TLS connection with the _DISABLE_TLS_ defi…

Notice that the code provided by @Apaezmx is not for ESP8266.
