We are trying to test Minio notifications using MQTT and with only certificates
Our configuration looks like below

export MINIO_NOTIFY_MQTT_BROKER_mqtt1="tls://<MQTT_host>:<MQTT_Port>"
export MINIO_NOTIFY_MQTT_TOPIC_mqtt1="<topic_name>"
export MINIO_NOTIFY_MQTT_QOS_mqtt1="1"
export MINIO_NOTIFY_MQTT_PUBLIC_CERT_mqtt1="app_user.crt"
export MINIO_NOTIFY_MQTT_PRIVATE_KEY_mqtt1="app_userkey"

But when we test, Minio is throwing below error

API: SYSTEM.notify
Time: 08:10:22 UTC 10/06/2025
DeploymentID: bee27b2f-91da-426e-81b2-73be7af5afe2
Error: bad user name or password (*errors.errorString)
targetID="mqtt1:mqtt"
3: internal/logger/logonce.go:118:logger.(*logOnceType).logOnceIf()
2: internal/logger/logonce.go:149:logger.LogOnceIf()
1: internal/event/targetlist.go:291:event.(*TargetList).sendSync.func1()

Can you please provide correct notify parameters for MQTT to achieve this?
