failed to get info for server %q: %w

Error message

failed to get info for server %q: %w

What it means

The Hetzner Cloud API call (Server.GetByID) failed or the server record lacks usable data while resolving the node's backing server. The %w detail carries the API error; authentication, network, or a deleted server are typical causes.

Solutions

1. Check the wrapped API error (auth token, rate limits, connectivity)
2. Verify the server ID still exists in the Hetzner project
3. Delete the stale Node object if the server was deleted
