Make sure Windows allows network connections to Adversus' servers.
Windows 11
When you first connect to a Wi-Fi or Ethernet network in Windows 11, it's set to public by default. This will greatly limit the network capabilities of web applications like Adversus and will most likely result in audio loss during calls.
Public network: Use this for networks you generally don't trust. You should use this in most cases, but please be advised that Adversus most likely will not work as expected unless you manually allow traffic to our servers.
Private network: Your PC will allow incoming connections and outgoing network traffic on a wider range of ports. Unless you manually allow Adversus' servers in the Windows Firewall, this is the recommended setting for allowing the needed connections to Adversus
Notice: If you know how to allow traffic to certain IP addresses and port ranges, you can find the needed information here.

When you first connect to a Wi-Fi or Ethernet network, you can set it as public or private. If you don't know how to manually allow traffic to certain IP addresses and port ranges, it is recommended to select private.
