Unable to connect to Sonos in App but system is working

So this is very odd.  I just got a full Sonos Arc system with the sub and rear SL1's.  So I get everything connected in the app and then plug the arc into my TV's ARC port via HDMI and it's working fine.  I watched a little bit of John Wick 3 on Vudu to hear how it sounds with the rears and it's great.  Turned on my PS5, same thing, sounds fantastic, but I can't use my app now.  When I start my app it keeps telling me Unable to login to Sonos now. 

It was working a little bit after the initial install, but oddly separated my rear SL's into living room 2 instead of my main living room with the arc and sub.  I brought them over from that room to the main living room, then it said my rear left wasn't connected, even though it was and working, so I tried to disconnect and re-configure them.  Let's just say it didn't work and then I was just getting sound out of 1 SL and getting a blinking white light on the other.

Fast forward a few hours.  Wife had to go to work, and I had to take kids to grandma's for some back up with all my kids.  I came home to take a quick shower, then was going to trouble shoot some more.  Turned on Vudu and boom, all speakers were connected and working again (wtf?).  So its all good now right?  Nope, my sonos app still won't connect to anything and all my options are greyed out.

I'm at a loss for what's happening.  Tech support is closed wanted to get some ideas from you guys.  Sorry for wall of text.  Again, it's working, but app is not so I can't configure or tinker with anything.

    Much more likely that your mesh network has her device connected to a different subnet. It’s one of the reasons you’ll see many of us users suggest that Sonos doesn’t always play very well with various mesh devices, depending on how they work, everything can be fine, or it can operate as you’re experiencing.

    Try wiring one Sonos device to the hub of your network, wait a couple of minutes for the Sonos to recognize the change, then test. I suspect it should work for both of you.

    If it’s untenable to leave one of your current devices connected to your router in your cutprrent environment, you can substitute a BOOST, as I have in my home.

    There’s more data in these links as well:

    Thank you for this. In my case I have verified that she is on the same subnet & vlan as I am. I have verified that she has firewall line of sight between the sonos devices from her machine via ping and http://sonosdevice:1400/tools.

    It just seems that SSDP discovery is blocked for her but not me (on the same subnet/vlan).

    It might be helpful to folks more savvy in networking if you were to provide model numbers / brands of your network devices, as well. I’m at my limit here.

    • Unifi Security Gatway (USG 3Pro; firewall/router)
    • Unify Nano Access Point (WiFi AP)
    • Various Unifi managed switches

    System configured with multiple subnets and vlans. Vlans are aligned on subnets (eg. 192.168.10.x is the “guest” vlan).

    The USG has mDNS & SSDP proxies enabled allowing both protocols to span all subnets/vlans.

    My mac & android phone work fine over wifi 5ghz band. My wife’s mac & iphone fail to work over the same wifi 5ghz band. All devices are on the same vlan/subnet.

    Any advice is greatly appreciated.

      Have you tried switching off “wifi assist” and/or “private address”?

      Good catch. However disabling both wifi assist and private address did not help. I fear I am going to have to break out a network sniffer and track discovery requests and their subsequent responses.
