To ensure your users can access Fuel Cycle without disruption, your internal information technology team must allow list specific Fuel Cycle domains on your organization's network and firewall. This step prevents corporate security tools, such as firewalls, web filters, or proxy servers, from blocking platform features, survey links, authentication requests, or asset delivery. These domains must be unblocked on your internal network, not on your public-facing website or web server.
Your community's URL should also be whitelisted.

FC Qual's live video and audio features are powered by Agora. The requirements below apply to clients in North America and Europe.
Per Agora's official documentation, whitelist by domain rather than by IP address. IP-based whitelisting applies only to Cloud Proxy mode.
Domains
The following wildcard domains cover all Agora services for both North America and Europe:
*.agora.io
