It worked perfectly without any error two days ago. But today, when I logged in, the space was sleeping. When it woke up, it showed starting. After 30-40 mins, the space suddenly just showed this:\n\n\"runtime error\n\nScheduling failure: unable to schedule\"\n\nIt happened with my other spaces which I created long ago. And the logs show:\n\n“===== Application Startup =====”\n\nI don’t know what is happening. Can anyone help me?\n\nSame issue for me, it looks like a HF issue\n\nThanks for sharing. I thought I am the only one having this issue. I was worried since I have a competition tomorrow and need to present a live deployed version.\n\nPerhaps due to a lack of resources, everything is back to normal now.\n\nI also think the underlying cause was a lack of resources, but it seems to have been a real issue on HF side: [Space stuck in APP_STARTING indefinitely - #6 by hysts](https://discuss.huggingface.co/t/space-stuck-in-app-starting-indefinitely/177564/6)", "url": "https://wpnews.pro/news/unable-to-schedule", "canonical_source": "https://discuss.huggingface.co/t/unable-to-schedule/177563#post_7", "published_at": "2026-07-09 21:57:54+00:00", "updated_at": "2026-07-09 22:16:50.589152+00:00", "lang": "en", "topics": ["ai-infrastructure"], "entities": ["Hugging Face"], "alternates": {"html": "https://wpnews.pro/news/unable-to-schedule", "markdown": "https://wpnews.pro/news/unable-to-schedule.md", "text": "https://wpnews.pro/news/unable-to-schedule.txt", "jsonld": "https://wpnews.pro/news/unable-to-schedule.jsonld"}}
