Socket error while trying to connect to mosquitto mqtt server

[ZeGuigui]

Hello

I am trying to configure mqtt client. Both zigate and mqtt server are on the same lan.

Zigate settings:

• Slip on serial port enabled
• MQTT hostname : 192.168.1.50
• MQTT port : 1883
• Client id : zigate
• Client timeout : 2s
• Keep alive: 60s
• Username and password : none

Mosquitto server (fresh install) :

• allow_anonymous: true
• IP: 192.168.1.50
• Port: 1883

I validated mosquitto install with mosquitto_pub, mosquitto_sub and MQTT Explorer

In mosquitto logs I can see:

1588369087: New connection from 192.168.1.55 on port 1883.
1588369087: Socket error on client <unknown>, disconnecting.

If I activate user authentication and give the zigate its user and password I get the same error, only its login is logged:

1588368809: New client connected from 192.168.1.55 as zigate (c1, k60, u'zigate').
1588368816: Socket error on client zigate, disconnecting.

Quick question while I am here: does it support tls?
