[SOLVED] MQTT not working after changing the broker ip

I have installed mqtt binding as well as edited the config file. My mqtt subscription was working until I changed the mqtt ip adrdess… Not sure what the error is
My items file s this.

Number home_temp "Living Room [%.1f °C]" <temperature> {mqtt="<[mosquitto:application/2/node/00000000000000/rx:state:JSONPATH($.object.adc)]"}

the url to the mqtt broker is this, earlier with another url it used to work but right now I need to get data from this broker ip.


The error logs

I edited the mqtt.config file and deleted the mqtt config file from user data folder, although the initial error is not there, I am still facing some issues, and mqtt is not subscribing
