Can, you try to swap the used protocol ? for exemple use the http/ws if you use https/wss or the reverse ?
If you want to downgrade, give me your OS I can give you the folder with all versions.
I don’t even know what protocol Home Assistant uses?
And even if switches helps - it’s still a way to remotly crash deCONZ. This should not be possible. This is a bug
There are no changes in protocols from the integration perspective, its the same as has always been.
I am seeing this too. Definitely some odd behaviour since updating to 2.32.
