Hello
When I send lock command to Nuki Ultra, Lock becomes unknown after 30 seconds. When you look at the logs of HA, in home assistant core it gives the error as below.
Logger: homeassistant.components.websocket_api.http.connection
Source: components/websocket_api/commands.py:317
integration: Home Assistant WebSocket API (documentation, issues)
First occurred: 1:49:29 AM (1 occurrence)
Last logged: 1:49:29 AM
[139831714351520] Error during service call to lock.lock: InteractionModelError: Failure (0x1)
And when also look at the HA Matter Server logs:
2025-10-29 01:49:29.053 (MainThread) ERROR [matter_server.server] Error doing task: Task exception was never retrieved
Traceback (most recent call last):

What can be the possible reasons of this problem? When I interview the lock I get all the information without problems. FW version 5.5.10.
