I am having a problem that seems somewhat similar. After months of successful use, Roon app running on 5 year old iPad connects to Nucleus+ across network (with router and switch) and Chord M Scaler endpoint, with 2 networked Audio Sources. But, then recently, cannot establish connection to the M Scaler. I have done some troubleshooting and consulted with my dealer. May open a case here, soon. Thanks.
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
I still have the problem.
But I think it comes from the wifi connection. Maybe the iPad changes the channel or the frequency.
When I restart, it’s better for a while.
I’m waiting the 2YU’s release with the 2go in replacement if the iPad. I hope it will be better.
