Troubleshooting

GitHub sign-in reloads without signing in

1. Confirm that you are running the latest Tellnova version.
2. Quit and reopen Tellnova, then retry sign-in.
3. Verify that the browser returned to the same development or production environment that initiated sign-in.
4. If repository permissions changed, sign out and authorize GitHub again.

Development and production use separate authentication deployments. A callback for one environment cannot establish a session in the other.

Git is missing on Windows

Install Git for Windows, then quit every running Tellnova process and reopen the app. A process started before Git was installed may still have the old PATH.

A provider says it is disconnected

Open Settings → Models and refresh the provider status. If the settings page shows a valid connection but the composer does not, close and reopen the composer after the refresh. For API providers, verify the base URL, key, and exact model identifier.

macOS says the app is damaged

Quit Tellnova and run:

xattr -cr /Applications/Tellnova.app

Do not run codesign on the installed application. See Install Tellnova for the full explanation.

The same update appears after restarting

Install the latest DMG manually once. Your Tellnova data lives outside the application bundle and remains in place. After copying the new application into Applications, run only the xattr command above.

A task cannot find a remote branch

A task can be checked out on another machine only after its branch has been pushed. Return to the machine that owns the worktree, push or open the pull request, then retry on the other machine.

Current checkout is unavailable

Current checkout requires a local folder containing a Git repository with at least one commit. It cannot be selected for a repository that exists only as a GitHub entry; choose its local folder first or use an isolated worktree.
