same fault over here since they went bancrupt. they where bought, but no new api was provided yet. contacted support and they will change as soon as new api is avail, but until then, you are lost (same like me)
as the callback to nello fails, this is a fail from their side not from athom. But complaining to nello didn’t changed anything for me until now. You may go ahead and also complain over there, maybe it will help and we both get the device back to working
