can't connect to MSTT server mosquitto #57

Closed frgithub35 closed 3 months ago

frgithub35 commented 3 months ago

Hi,

I've just installed a new MQTT mosquitto broker version 1.5.7 (https://mosquitto.org/man/mosquitto-8.html) It supports MQTT protocol version 5.0/3.1.1/3.1 I have no problem with other application like MQTTExplorer or arduino IOT

I can't connect to it with or without user/password with or without TLS with or without Websocket

the logs are : 2024-07-24 10:49:29 INFO sk.mimac.slideshow.mqtt.MqttService - Connecting to MQTT server '192.168.1.10' and topics 'SLIDESHOW/REQ/AndroidTV/+' 2024-07-24 10:49:30 WARN sk.mimac.slideshow.mqtt.MqttService - Error in MQTT connection com.hivemq.client.mqtt.mqtt5.exceptions.Mqtt5ConnAckException: CONNECT failed as CONNACK contained an Error Code: UNSUPPORTED_PROTOCOL_VERSION.

Hello @frgithub35,

Mosquitto 1.5.7 doesn't support MQTT 5.0, as the support was added in Mosquitto 1.6 (https://mosquitto.org/blog/2019/04/version-1-6-released/). I highly suggest upgrading to Mosquitto 2.x, we are using Slideshow with Mosquitto 2.0.11 on multiple projects without any issues.

Hi, I thought I was up to date with my version of mosquitto, but it was installed on an old Debian. I updated all that and everything's back in order Thanks again for this
