Communication Failed about ha_tuya_ble

[CH1PSET1]

Came here to create a question for exactly the same problem, but I was already beaten to it.
Actually exactly the same situation. CUBETOUCH II works fine in HA, but after an indefinite time, my CUBETOUCH II disconnects and the connection is no longer established. And most importantly, restarting the integration doesn't help either, only restarting the entire HA.
CUBETOUCH II can work for a week, or maybe 2 days, and the moment of shutdown is also not so easy to determine. According to the device logs, it says that the interaction is taking place, but physically CUBETOUCH II does not react, then you reload the integration and CUBETOUCH II goes into the unavailable state and nothing more can be done.
In general, such logs often go:
2023-08-01 01:43:04.685 WARNING (MainThread) [custom_components.tuya_ble.tuya_ble.tuya_ble] DC:23:4F:01:56:29: Device unexpectedly disconnected; RSSI: -67
But this does not prevent CUBETOUCH from working stably. (and the distance to bluetooth 2 meters line of sight).
And then, with complete inaccessibility, the following logs appear:
The above exception was the direct cause of the following exception:

I would like to know what is causing this and fix the problem.
Or at least catch the problem as it occurs and fix it (preferably without rebooting the entire HA system).
I'm even ready to put a trigger that would perform some actions every few hours to keep CUBETOUCH running all the time.

Same boat here, with dongle directly connected to server,
and it's only device acting up like this
also in the logs:
This error originated from a custom integration.

After a while, tuya_ble get tired of trying to connect without receiving response and stop polling the device:

Could it be the version of the Cubetouch II firmware (v1.5)?

[esguti]

I have reinstalled the plugin and both Cubetouch are working fine.
