About the problem
If you or your company uses a firewall, Copilot may not function as expected. Copilot interacts with a remote machine learning model and checks for updates, and a firewall may block important traffic and degrade the user experience.
Solving the problem
For an optimal Copilot experience, you should create an "allowlist" that lets certain URLs, ports, and protocols through your firewall. See Configuring your proxy server or firewall for Copilot.
