If you're seeing below error window or error message Device cannot connect to any wireless network or Network not available, you may need to allow access to additional hosts through your firewall.
The hosts listed below must be accessible via HTTP port 80 in order for VibeOS to detect the device as connected to the Internet. If your firewall supports wildcards, you may be able to use a wildcard to allowlist alt*.gstatic.com.
In addition to allowing these hosts through your firewall, if you perform TLS or SSL inspection on your network, you’ll need to also follow the instructions on how to Set up a hostname allowlist.
