Can't connect on Windows 10 with Sonos Controller

Hello,

I’m unable to connect to my Symfonisk using the Sonos controller app (61.1.82310) on Windows 10 (64-bit, version 20H2), even though all is working fine from Android.

The Symfonisk is connected to the wireless network.

The PC is connected to the same router via ethernet cable.

Both devices obtained a DHCP IP address in the same class C network (192.168.255.x)

I’ve been searching the forums and checked all possible issues I could find:

  • the PC ethernet connection is using the Private profile
  • Windows firewall rules for Sonos are in place (the controller s/w did that)
  • I can ping the Symfonisk from the PC
  • I can see the Sonos Support Info page on the browser on the PC (http://192.168.255.21:1400/support/review)
  • I’ve disabled the firewall and the AV (Windows Defender), the problem remains

What am I doing wrong?

Thanks in advance.

For the record, I’ve found what the issue was.

The problem was with my VPN client (Check Point Endpoint Security).

This VPN client includes an embedded firewall that sits in tandem with Windows native firewall.

I knew that.

What I didn’t realize was that it stays active even when the VPN client is not running. It sits there, blocking whatever inbound traffic it doesn’t like, even when the VPN client is shutdown.

So the only option is uninstall.

After I did that, voilá, the controller immediately found my devices.

Not happy with myself, I should have known better.

Hi @controlav ,

I’ve installed it, can't find the player also

How can I get to the diag file?

Should I sent it to your support e-mail address?

Cheers,

If you hit the Help button, it will send me an email allowing me to look at the diagnostics.

    Interesting, usually VPNs show up in the network diagnostics, but there was no sign of it in yours.

    Check Point states that it uses stealth technology.

    It seems to hide itself pretty well from diagnostics running inside the host, so this is more than marketing sound bites.
