Temperature sensor started pairing, then lost

I started pairing one more temp sensor (paired two before that one, and another one after).

HA showed the initial dicovery, then hung up there, while the sensor exited from pairing mode (no more flashing icon on display). After that, i cannot pair it anymore. When i start adding a new device, the sensor doesnt appear while in pairing mode.

Of course, the sensor does not appear on the zha topology view, and i cannot see the entities.

I tried to recycle ZHA and pull the battery from the sensor.

Maybe the sensor address got stuck somewhere in ZHA?

Any way to check?

thank you.

after one hour or so it paired.
