I moved apartments and now the sub is not connecting to the Arc sound bar. However, I’m able to connect the sub to other sound bars. Arc is the only sound bar that the sub will not connect to. 

Here’s the most recent diagnostics code: *

Can someone from support assist?

Unfortunately, support doesn’t live in these community forums, you have to call Sonos Support directly to discuss that diagnostic. 

There are two possibilities that I can think of, since I don’t have access to diagnostic data. First would be the ‘radio/wifi’ has been turned off on the Arc for some reason. Because the Sub connects via a hidden (to us) 5Ghz WiFi signal, it needs to be on. On both the Sub and the Arc, now that I think of it….but you said the Sub connects to other Sonos devices, so it’s likely the Arc. And if it ‘appears’ to be on, I’d turn it off, wait a minute, then turn it back on, I’m paranoid.

The other possibility, that no one in this community would be able to see, is a hardware failure, something I would think might show up in your diagnostic. Resolving that issue would require direct Sonos intervention anyway.
