to phachakorn:
Please check Communication Lines->Request Sequence -> Column Command Line.
You need to write KpMqtt_Config.xml in this column and than Upload Configuration.
If a file name KpMqtt_Config.xml has already been written in this column, just Upload Configuration.

to ALnaluk:
Please show connection settings in working mqtt-spy and compare with <MqttParams Hostname=”tailor.cloudmqtt.com” ClientID=”” Port=”15043″ UserName=”pscmbdmc” Password=”pscmbdmc”/>

UPD to ALnaluk:

Hi,

Try installing the up to date version of KpMqtt.dll. May be it doesn’t fix the error, but the new version provides the detailed error message (link).
