My network ignoring devices to join

[bigboban]

I have HA + zigbee2mqtt plugin + Slaesh zigbee USB coordinator. Everything was fine for months. But now i had problem with one devices (Ikea Fyrtur). So i tried to re-join but it is not possible. I tried some other devices (Xiaomi button, Ikea button) i used before without problem. but my zigbee networks IGNORES any join try. I have join permitted of course. But after join try (in most cases some long push of hidden button) NO LOG MESSAGE about joining in zigbee2mqtt log.

I am able to remove device from network but i am NOT able to rejoin any way. I restarted zigbee2mqtt, restarted HA, removed Slaesh from USB and put back. Nothing helped.

Please help how to make joining working again.

Same problem here with same USB coordinator slaeh's CC2652RB stick.
The network is running fine and joining used to work. Sometimes I had to reboot the RPI to allow joining. Now it does not work at all.
