I cannot access Figma (the main figma.com domain, any other subdomain is accessible, e.g forum.figma.com, status.figma.com, etc.) unless the firewall is disabled on my network under Windows 11 Security.
Neither is it accessible from Firefox and the desktop app, nor from other browsers. However, from other devices it seems to be working. Any port connection manipulating firewall rules, that I know to previously have been created, have been disabled. The browsers, operating system and most drivers are up to date. It is also not working with extensions disabled and disabling the browser’s use of Proxy does nothing.
This is the error that the desktop app displays:

Update: it has to be a problem on my home network, since on mobile network sharing from my phone it loads in.
