It looks webcore (or smartthings) doesn’t send GET web requests using TLS 1.2
I am trying to reach “Telegram bot api” using:
Make a GET request to: http://api.telegram.org/…
but sadly it started to fail lately with error:
Error executing external web request: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
As stated on Telegram twitter page, Telegram Bot API doesn’t support TLS 1.1 anymore:
@ady624 is this a bug on webcore or smartthings side ? Can this be fixed with any incoming updates ?
