ChatGPT Vercel MCP returns 404 for a new project after reconnect

The ChatGPT Vercel MCP connection can list two older projects, but it does not list a newly created project in the same team. Looking up the new project by its exact ID returns 404.

I reauthorized the team and reconnected the existing Vercel connection as recommended by support, but the issue persists. The connection has permission to read and modify authorized projects, but I cannot see a project selector.

Could the Vercel MCP team check the effective project authorization and advise how to restore access? Please let me know a private channel where I can provide the project ID and diagnostics.

There's another community post with 404 debugging tips that might be helpful. Please give these solutions a try and let us know how it goes.
