  "textContent": "Multiple causes are possible, and other factors may also be involved, so without build logs, nothing can be determined:\n\n* * *\n\n## What “Building” means on Spaces\n\nOn Hugging Face, **“Building” is a coarse status** that can cover multiple backend phases:\n\n  1. **Build** : install dependencies / build an image\n  2. **Registry** (mostly Docker): push/pull the image\n  3. **Scheduling** : allocate hardware and start the container\n  4. **Health check** : your app must start and **bind to the expected port** ; if it never becomes “healthy,” it may look like it’s still building or it fails after a while (Hugging Face Forums)\n\n\n\nSo the key is to **classify which phase you’re stuck in** , using logs.\n\n* * *\n\n## 5-minute triage playbook\n\n### 0) Confirm it’s not a platform-wide problem (30 seconds)\n\n  * Check Hugging Face status: **Spaces** and **Spaces Proxy** should be “Operational.” (Hugging Peace Status)\nIf there’s an incident, _many_ users see “Building” loops at the same time and your code changes won’t help.\n\n\n\n* * *\n\n### 1) Reproduce with a “known-good” minimal Space (2 minutes)\n\nCreate a minimal hello-world Space (e.g., a tiny Gradio demo or template). If **a blank/minimal Space also gets stuck** , your issue is likely **not your repo** but **infra/queue/account-side** (scheduler backlog, proxy, stuck builder). This exact inference is repeatedly used in recent forum triage guidance. (Hugging Face Forums)\n\n* * *\n\n### 2) Use logs to classify the failure (most important)\n\nOpen the Space → **Logs** and check **both** :\n\n  * **Build logs** (dependency install/build steps)\n  * **Container/Runtime logs** (your app starting/crashing)\n\n\n\nThis is the standard first step recommended by HF docs and common support replies. (Hugging Face Forums)\n\n* * *\n\n## Interpret the result (decision tree)\n\n### A) **Logs are empty / don’t load / show nothing happening**\n\nThis usually points to **infra/queue/scheduler issues** rather than your code. Similar reports describe “empty logs” during infra problems and recommend retrying later or escalating. (Hugging Face Forums)\n\n**What to do**\n\n  1. Space Settings → **Restart**\n  2. Make a **no-op commit** (edit README) to force a new build\n  3. Space Settings → **Factory reboot**\n  4. If minimal new Spaces also have empty logs, escalate (see “What to report” below). (Hugging Face Forums)\n\n\n\n* * *\n\n### B) Build says **“Build Queued”** or runtime shows **“Scheduling failure: not enough hardware capacity / Unable to schedule”**\n\nThat’s a **capacity/scheduler** bottleneck (common at peak times or for certain hardware). (Hugging Face Forums)\n\n**What to do**\n\n  * Retry later (queue clears), or switch to a different hardware tier if possible.\n  * Duplicating/recreating sometimes lands you on a different worker (works as a workaround in several “permanently building” reports). ([Hugging Face Forums](https://discuss.huggingface.co/t/space-is-permanently-building/140495 \"Space is permanently \"Building\"\"))\n\n\n\n* * *\n\n### C) Build fails with registry errors like **`spaces-registry… 401 Unauthorized`**\n\nThis is typically **HF registry/infra/auth** , not your app code, and is tracked in issues and forum posts. ([GitHub](https://github.com/huggingface/datasets/issues/7530 \"How to solve \"Spaces stuck in Building\" problems #7530\"))\n\n**What to do**\n\n  * Retry later; if persistent, report it with logs (see below) and reference that it’s a registry auth failure.\n\n\n\n* * *\n\n### D) After ~30 minutes you get: **“Launch timed out, space was not healthy after 30 min”**\n\nThis means the container started, but **HF never saw a healthy web service** (usually wrong **host/port** , app stuck during startup, or server never comes up). HF staff explicitly describe the expectation: your service must bind to the exposed port within the health timeout. (Hugging Face Forums)\n\n**Common fixes**\n\n  * **Bind to`0.0.0.0`**, not `127.0.0.1` (especially for Flask/FastAPI/custom servers). Forum replies repeatedly show this as the fix. (Hugging Face Forums)\n\n  * **Port mismatch** :\n\n    * For **Docker Spaces** , default exposed port is **7860** unless you set `app_port` in README YAML. (Hugging Face)\n    * For **Streamlit** , the SDK expects Streamlit conventions (port mismatch is a common pitfall). (Hugging Face Forums)\n  * App doing heavy work at startup (large downloads/installs) → move to build step / cache, or slim startup.\n\n\n\n\n* * *\n\n### E) Build succeeds, but container logs show crashes (imports, missing env vars, etc.)\n\nThen it’s your app/runtime configuration. Common culprits:\n\n  * Missing **Secrets/Variables**\n  * Wrong README YAML (`sdk`, `app_file`, etc.)—the YAML reference is the canonical source. (Hugging Face)\n  * OS packages: use `packages.txt` for apt dependencies (Gradio/Streamlit SDKs) and `requirements.txt` for Python deps. (Hugging Face Forums)\n\n\n\n* * *\n\n## “Even new Spaces aren’t loading” — what that usually implies\n\nIf **a fresh hello-world Space** also stays on “Building,” the most likely buckets are:\n\n  * **Platform-side** (Spaces/Spaces Proxy/infra backlog) (Hugging Peace Status)\n  * **Account-wide scheduling/build issues** (queue or stuck builder) (Hugging Face Forums)\n\n\n\nIn that situation, don’t spend time rewriting your app: focus on **logs + minimal reproduction + reporting**.\n\n* * *\n\n## What to collect before posting for help (or contacting support)\n\nInclude:\n\n  * Space URL(s)\n  * Whether a **minimal blank Space** reproduces\n  * **Build log tail** + **first runtime error** from container logs\n  * Timestamp and (if you see it) any backend trace identifier (some restart errors show a request/trace ID that staff can use).
