Can Flexy connect to AWS IoT on port 443? - thitoshi - 14-01-2022

Hello,

I'm afraid some firewalls might block port 8883.

https://aws.amazon.com/blogs/iot/mqtt-with-tls-client-authentication-on-port-443-why-it-is-useful-and-how-it-works/
The site says TLS client must support ALPN (Application Layer Protocol Negotiation) to connect AWS IoT on port 443.

Does Flexy support ALPN in Java?

Hi,

That is a very good question and the answer is unfortunately no, the Flexy does not support ALPN.
