Description

I run emqttd with tls enabled on port 8883 and get multiples of the following errors. Any help would be greatly appreciated. Thanks!

@ralphtheninja The crash means SSL handshake timeout, please check the handshake_timeout config in etc/emq.conf:

mqtt.listener.ssl.handshake_timeout = 15

@ralphtheninja Use the 8884 port for WebSocket/SSL connections

This was related to Azure Load Balancer pinging the service through a probe. However, it seems the ALB doesn't handle ssl connections.
