Using the documented AllowLANTraffic toggle does not allow SSDP. https://github.com/Windscribe/Desktop-App/wiki/Linux-CLI-configuration-file-reference
The Windscribe CLI firewall blocks SSDP/multicast like it’s guarding state secrets.

Linux CLI v2.20.4-alpha
To Reproduce
Enable AllowLANTraffic toggle in config
Enable firewall
Try to detect TV/printer/chromecast
fails
Expected behavior
AllowLANTraffic toggle allows SSDP, or:
Maybe an additional setting in the CLI config like allow_ssdp=true that lets multicast packets survive the firewall. That way our Chromecasts, TVs, printers, and weird IoT junk can exist without dropping the firewall entirely.
