Hello, this looks like the mqtt broker dropping the connection - not sure why though.

use: homeassistant.local is ok

can you elaborate on this?

[flamestsui]

use: homeassistant.local is ok
but use dsm.xxx.xxx is not ok
use python mqtt to ha is ok,but app is fail

[flamestsui]

In the settings, set it to homeassistant.local and it can be used normally.
However, if the IP is set to the domain name (the domain name points to the same point), it will not work.
The same domain name can be submitted to HA using MQTT using Python, but the App cannot.

Does it also work in HASS.Agent if you put plain IP in the "Broker IP Address or Hostname" field?

[flamestsui]

No way either
