Was doing some non-Sonos related troubleshooting on my network, and noticed that the pages normally found at player-ip:1400/support/review no longer seem to load. After I finished maintenance on my network, rebooted the network and Sonos gear, but nothing changed, the diagnostics/review pages still don't load. The 9.3 update installed a few days ago. Could this be related?

UPDATE: As is often the case, Sonos is not at fault, but my network was misbehaving. Apparently my router had decided to start handing out IPs in a different subnet, which caused my bookmark to the Sonos page to stop working. This also explained the non-Sonos related network issues I was actually analyzing.
