Hi @SunHeming,
We are currently working on adding ALPN support (which is required to use port 443) to the OpenSSL network layer.
I will keep this issue open and update it when we push the ALPN changes to master.
Thanks!

Hi @SunHeming,
ALPN support has been added in this commit. You can now use the additional constructor for the OpenSSL network layer to initialize ALPN (ie. when using port 443 for MQTT).
Please let us know if you have any more questions and if not close this issue.
Thanks!
