Can't generate MCP preview" on all components connected to self-hosted GitLab

Hi Figma team,

We're setting up Code Connect for our design system and the MCP preview in the Code Connect UI always shows "Can't generate MCP preview right now. Please try again later." It happens on every connected component.

Our setup:
- Code is hosted on a self-hosted GitLab instance (gitlab.atida.com), private repository.
- Components are connected at the component set level from the Code Connect UI, using the GitLab file URL (e.g. https://gitlab.atida.com/<group>/<project>/-/blob/main/src/components/Button/Button.tsx) and the exported component name (Button).
- We also published parserless Code Connect templates for the same components.
- The components show as "Connected", and the design context returned through the Figma MCP server includes the connected component correctly.
- We tried removing the local file-path connection and keeping only the GitLab one: same result.

Questions:
1. Does the Code Connect MCP preview support self-hosted GitLab repositories, or only repositories connected through the GitHub integration?
2. If GitLab isn't supported, is it on the roadmap, and is there a recommended alternative (e.g. Code Connect CLI, a GitHub mirror) to get the preview working?
3. Does the preview need the library to be published after the connection is made?

Plan: Organization

Thanks!
