When accessing the Figma desktop app using a proxy like Zscaler, you may encounter the error Blocked navigation to gateway.zscloud.net (or some other Zscaler-specific domain).
The Figma desktop app allows you to safe-list non-Figma origins used by the Zscaler ZIA proxy service to get everything to load within the desktop app. We recommend reaching out to your IT admin to confirm and safe-list the Zscaler ZIA domains in Figma.
You will need to configure the AllowedOriginHosts setting to reflect the domain(s) appropriate for your Zscaler ZIA configuration. Commonly the two values will be https://*.zscloud.net and https://gateway.zscaler.net. See the linked articles below for more information on how to set those values.
