- [x] 我已经搜索了 [现有 issue](https://github.com/DIYgod/RSSHub/issues)，以确保该错误尚未被报告。

Start with the /hebtv/nbszxd route and reproduce the reported request to the Hebei TV URL, then review the related route documentation at https://docs.rsshub.app/routes/hebtv. Investigate why the self-hosted deployment receives 403 Forbidden and identify a project-compatible way to restore fetching. Done means the route can normally fetch and serve its feed content.
