Feature Request: Options to pass ALPN and SNI while connecting to AWS IoT

Feature Request: Unable to connect to AWS IoT MQTT with custom authorizers

Hi,

We are using Hivemq-mqtt-client in our MQTT solution. It is working fine for connecting to MQTT brokers like: HiveMQ, VerneMQ, RabbitMQ.

We have a requirement to connect to AWS IoT. There are two options -- One using certificates, other using custom authorizers. While using custom authorizers (username and password and lambda functions), we must pass ALPN and SNI for it to work. https://docs.aws.amazon.com/iot/latest/developerguide/custom-auth.html#custom-auth-mqtt

Is there an option to pass these values to connect to AWS IoT?

Hi @onlybytes SNI is already supported out of the box. Unfortunately ALPN can currently not be configured, so we accept this as a feature request.

Hi @SgtSilvio

Many thanks

Hi! Any updates on this? ALPN seems to become more and more used, especially with cloud-based brokers.
