  "textContent": "Hmm… If the symptom is really “stuck in `PAUSED`”, **my personal impression is** that many of these cases do not get fixed until `website@huggingface.co` looks at them from the backend side. There are exceptions, of course, but I would treat this as a Space-state / lifecycle / possible moderation-lock issue first, not as a normal app crash. Details:\n\n* * *\n\nSmall note first: the Space URL in the post is still a placeholder, so nobody outside HF can inspect the actual repo/logs yet. But as a general decision tree, I would debug this by separating `503` from `PAUSED`.\n\n`503` alone is generic.\n`PAUSED` + restart failing + factory rebuild failing + commits not dispatching a new build is the more important pattern.\n\n## Quick decision tree\n\nWhat you observe | Most likely bucket | First useful check | Next action\n---|---|---|---\nBuild logs update and show an error | Build failure | Build log | Fix dependency/Docker/build error\nContainer logs update and show a traceback | App/runtime crash | Container log | Fix app crash, missing env vars, model download, etc.\nApp logs say it is running, but browser shows 503 | Port/healthcheck/routing issue | Port, host binding, `app_port`, healthcheck | Fix Space config / server binding\nRestart and Factory Rebuild fail, commits do not trigger build, logs do not update | Space lifecycle / builder dispatch / stuck state | Runtime API | Likely needs HF-side inspection\nRuntime API says `Flagged as abusive`, `abuse-handler`, `RepoScanner`, `Cloudflare`, `tunnel`, `proxy`, etc. | Moderation / scanner / policy lock | Runtime API `raw` / `errorMessage` | Email HF with evidence and ask for review\nMany unrelated Spaces/users affected | Platform incident | HF status page | Wait / follow incident\n\nSo I would not conclude the root cause from `503` alone. But if the Space is really stuck in `PAUSED` and no build is being dispatched, I would stop pushing repeated commits and first inspect the runtime state.\n\n## First check: Space runtime state\n\nHugging Face documents runtime-management APIs in `huggingface_hub`, including `get_space_runtime()`, `fetch_space_logs()`, and `restart_space()`:\n\nhttps://huggingface.co/docs/huggingface_hub/en/package_reference/space_runtime\n\nTry this locally:\n\n\n    from huggingface_hub import HfApi\n\n    api = HfApi(token=\"hf_xxx\")  # useful if the Space is private\n    runtime = api.get_space_runtime(\"OWNER/SPACE_NAME\")\n\n    print(\"stage:\", runtime.stage)\n    print(\"hardware:\", runtime.hardware)\n    print(\"requested_hardware:\", runtime.requested_hardware)\n    print(\"raw:\", runtime.raw)\n\n\nOr inspect the raw endpoint:\n\n\n    https://huggingface.co/api/spaces/OWNER/SPACE_NAME/runtime\n\n\nWith auth:\n\n\n    curl -H \"Authorization: Bearer $HF_TOKEN\" \\\n      https://huggingface.co/api/spaces/OWNER/SPACE_NAME/runtime\n\n\nLook for:\n\n\n    stage\n    hardware\n    requested_hardware\n    raw\n    errorMessage\n    abuse / moderation-related fields, if present\n\n\nImportant words to notice:\n\n\n    Flagged as abusive\n    abuse-handler\n    RepoScanner\n    Cloudflare\n    tunnel\n    proxy\n    trojan proxy\n\n\nIf any of those appear, this is probably not a normal build failure.\n\n## Practical branch guide\n\n### Branch A — Runtime output shows an abuse / moderation / scanner message\n\nIf the runtime output says something like:\n\n\n    Flagged as abusive\n    abuse-handler\n    RepoScanner\n    Cloudflare\n    tunnel\n    proxy\n    trojan proxy\n\n\nthen I would treat it as a HF-side review case.\n\nThat does **not** prove that you intentionally did anything wrong. It only means the Space may be paused by an automated scanner or policy mechanism, and more commits may not unlock it.\n\nIn that case, I would email `website@huggingface.co` with a compact, evidence-heavy report:\n\n\n    Subject: Space stuck in PAUSED / 503 loop - possible false positive or lifecycle lock\n\n    Space URL:\n    HF username:\n    Request ID:\n    Exact failed restart time, with timezone:\n    Runtime API output:\n    Build log status:\n    Container log status:\n    SDK type:\n    Hardware:\n    Last known working commit:\n    Recent changes:\n    What the Space does:\n    Why it is not a proxy/tunnel/relay/scraper/spam/abuse service:\n    Any suspicious files/dependencies already removed:\n\n\nThe key is to give HF enough backend correlation data: Space URL, Request ID, timestamp, and runtime output.\n\n### Branch B — No abuse message, but build never starts\n\nIf there is no moderation/scanner message, but:\n\n\n    Space remains PAUSED\n    Restart returns 503\n    Factory Rebuild returns 503\n    New commits do not trigger a build\n    Build logs do not update\n    Container logs do not update\n\n\nthen I would still treat this as a Space lifecycle / builder dispatch / stuck backend state issue.\n\nForum users usually cannot see the builder queue, lifecycle record, or backend restart error. This may still need HF-side inspection even if it is not an abuse/moderation case.\n\n### Branch C — Build/container logs do update\n\nIf logs update, then debug it as a normal Space issue.\n\nCommon checks:\n\n  * dependency install failure\n  * Python traceback\n  * missing secret / missing environment variable\n  * model download failing at startup\n  * startup taking too long\n  * server listening on the wrong port\n  * server binding to `127.0.0.1` instead of `0.0.0.0`\n  * Docker `app_port` mismatch\n  * Dockerfile `EXPOSE` mismatch\n  * healthcheck/readiness problem\n\n\n\nFor Docker Spaces, the normal docs to check are:\n\nhttps://huggingface.co/docs/hub/spaces-sdks-docker-first-demo\n\nFor Space metadata/configuration, including startup timeout:\n\nhttps://huggingface.co/docs/hub/en/spaces-config-reference\n\n### Branch D — Possible platform incident\n\nAlso check:\n\nhttps://status.huggingface.co/\n\nA green status page does not rule out a single-Space or account-specific issue, but if there is an active Spaces / Spaces Proxy incident, changing your repo may not help.\n\nWhy I would not over-focus on the missing Space URL (click for more details) Close public cases: similar pattern, not proof (click for more details) Partially similar cases: lifecycle / builder / scheduler stuck (click for more details) Similar-looking but probably different cases (click for more details) Policy-sensitive patterns: why Cloudflare/proxy/tunnel wording matters (click for more details)\n\n## What I would avoid for now\n\nI would avoid:\n\n  * pushing many empty commits before checking whether the builder is actually starting\n  * assuming `503` automatically means an abuse flag\n  * assuming it is only an app bug if no logs are updating\n  * deleting random files without checking the runtime output first\n  * posting tokens, secrets, full environment dumps, or private logs publicly\n  * creating many duplicate Spaces before knowing whether this is account/namespace/lifecycle-related\n\n\n\nA small duplicate/minimal Space test can be useful, but if the issue is account-side or lifecycle-side, many duplicates may just add noise.\n\n## Final practical recommendation\n\nI would treat this as a decision tree:\n\n\n    Does runtime API show abuse/scanner/policy wording?\n      -> Email HF with Space URL, Request ID, runtime output, timestamps, and legitimate-use explanation.\n\n    No abuse/scanner wording, but build never starts?\n      -> Still likely needs HF-side inspection; report it as a lifecycle/builder/PAUSED-state issue.\n\n    Build/container logs update?\n      -> Debug as a normal app/build/container/healthcheck issue.\n\n    Many Spaces affected?\n      -> Check HF status before changing repo code.\n\n\nSo yes, if the Space is genuinely stuck in `PAUSED`, my first serious path would be `website@huggingface.co` with the runtime API output attached. The Space URL is still needed for a concrete answer, but the general diagnosis path above should help decide whether this is app-level debugging or an HF-side Space-state issue.",
