Framer Agent 0.0.44 — “No connection to the server” at createSession

Hi! I'm unable to create an External Agent session for a Framer project using Codex.

The project opens and works normally in the Framer editor, but @framer/agent consistently fails when creating the headless session:

Failed to create session: FramerAPIError: No connection to the server

With the official --debug flag, everything succeeds until:

session.new: calling createSession on relay...

and then immediately fails with the error above.

What I've already verified:

• Framer Agent: 0.0.44 • Relay: healthy, running 0.0.44 • Node.js: v26.7.0 • npx @framer/agent setup completes successfully • Stored credentials are found and recognized for the correct project • Both the project ID and full Framer project URL resolve correctly to the same project • VPN on/off makes no difference • DNS, TCP and TLS connectivity to api.framer.com work normally • The WebSocket endpoint wss://api.framer.com/channel/headless-plugin is reachable • A manual unauthenticated handshake reaches the endpoint and returns the expected validation error for the missing projectId • Restarting the computer, browser, Wi-Fi/router and reinstalling the Agent setup did not change the result • The failure was reproduced from separate Codex sessions

Relevant debug sequence:

credentials: using cached API key relay: server version=0.0.44 relay: version matches, no action needed relay: relay server ready session.new: credentials resolved for project=... session.new: calling createSession on relay... Failed to create session: FramerAPIError: No connection to the server

No project changes or publishing actions were performed during these tests.

Is there currently a known issue with External Agents / the headless-plugin createSession flow, or is there another diagnostic I should run?

Any help would be greatly appreciated. Thanks!
