Debugging is difficult based on that information alone…

Here is a beginner-safe, step-by-step way to debug your paused Space that cannot restart and only shows a Root=1-... ID.

I will walk through:

  1. What that situation usually means
  2. A simple decision tree to classify the problem
  3. Step-by-step debugging for each case
  4. Safe actions you can try from the UI only
  5. When to stop and contact Hugging Face with that Root ID

At the end there is a short bullet summary.

0. Background: what is going on when a Space is “paused” and restart fails

Very short background.

  • A Space is a small app (Gradio, Streamlit, Docker) running on Hugging Face hardware.(Hugging Face)

  • It has states like Building, Running, Paused, Error.

  • The platform can auto-pause or auto-suspend your Space if:

  • When you click Restart, the Hub:

    1. Schedules some hardware
    2. Rebuilds or reuses the image
    3. Starts your app and waits for it to become healthy

When something in that flow fails, the UI sometimes only shows:

Error with a request ID such as Root=1-6938d880-3c2a37cf5f60af613ce8d7b0

That string is a request ID that Hugging Face can use to find internal logs of the failed restart. It does not tell you the root cause directly. It only proves “the restart API call failed at some point”.

So you debug by answering two questions:

  1. Did my app or build fail
  2. Or did the platform fail before my app even ran

1. First: classify your problem in three minutes

Open your Space page in a browser.

1.1 Check the top banners and status

Look for:

  • A colored banner like:

    • “This Space has been disabled”
    • “This Space has been marked abusive”
    • “Scheduling failure: Unable to schedule” or “not enough hardware capacity”(Hugging Face Forums)

  • The status chip near the title:

    • Paused
    • Building
    • Running
    • Error

This already tells you a lot.

1.2 Click “Restart this Space” once

Then observe:

  1. Does status stay Paused, and you immediately get an error dialog with Root=... and nothing else changes

    • Likely restart API / infra / moderation issue

  2. Does status change to Building, then after some time to:

    • Error
    • or back to Paused
    • and logs show something
    • Likely build-time or runtime problem in your app

  3. Does status change to Running, and you only see errors when opening the app or calling its API

    • Likely app-level bug, not Space lifecycle

We now handle each case.

2. Case 1: Space never leaves “Paused” and restart only shows Root=...

This is the one that feels the most mysterious. It matches several forum threads where:

  • Restart or factory reboot fails with 5xx
  • Logs do not update
  • Sometimes logs cannot be loaded at all and show “Failed to load logs: Not Found”(Hugging Face Forums)

2.1 Simple checks

Do these:

  1. Try restart only 1–2 times

    • Do not spam the button. It does not help and can confuse you.

  2. Open the Logs panel anyway

    • Click “Logs” or “View logs” on the Space page.
    • Check whether new entries appeared at the time you clicked restart.

  3. If no new logs and the Space status stays Paused:

    • The failure is likely before your app or build, inside the scheduling or restart system.

  4. Check for moderation / abuse banners again

    • If you see any “abusive / disabled” text, that is a moderator flag and you cannot clear it yourself.

2.2 Beginner-safe actions you can still try yourself

All from the web UI. No CLI required.

  1. Tiny commit to trigger a clean rebuild

    • In the “Files” tab, edit README.md.
    • Add one character or a short note like “test rebuild”.
    • Commit.
    • This forces the builder to run again, which sometimes clears a stuck state that appeared while your Space was paused during some internal upgrade.(Hugging Face Forums)

  2. Run a Factory reboot once

    • Go to Settings → Runtime / Hardware.
    • Use Factory reboot. This rebuilds the Space image and clears its cached layers and ephemeral storage.(Hugging Face)

  3. Switch hardware one time

    • In the same settings page, change hardware from your current type to another flavor, for example from CPU basic to CPU upgraded.
    • Save and let it build.
    • Optionally change back later.
    • Multiple users report that this forces the scheduler to place the Space on a fresh host and can unstick builds.(Hugging Face Forums)

If after these three steps you still:

  • See only Root=...
  • Get no new logs
  • Or see “Failed to load logs: Not Found”

then this is very likely an infra or moderation issue.

2.3 When to stop and contact Hugging Face

At this point you stop trying to fix it yourself.

Prepare this information:

  • Space URL

  • Your HF username

  • Time (with timezone) when you last tried to restart

  • The full error line with Root=1-6938d880-3c2a37cf5f60af613ce8d7b0

  • A short note saying:

    • Space is paused
    • Restart and Factory reboot fail
    • No new logs appear, or logs cannot be loaded

Then:

  • Open a thread in the Spaces or Beginners category of the Hugging Face forum, or
  • Use the official support form

Forum threads from other users with the same pattern were resolved only when HF staff checked internal flags and logs on their side.(Hugging Face Forums)

That is where your Root=... ID is actually useful.

3. Case 2: Space goes to “Building”, then “Error” or back to “Paused”

Here your restart is working at the platform level. Your app or build is failing.

This is where a beginner-safe log reading method helps.

3.1 Understand build logs vs runtime logs

On your Space page:

  • Build logs

    • Everything that happens while the image is created.
    • Installing dependencies from requirements.txt, running Dockerfile steps, cloning the Git repo.(Hugging Face Forums)

  • Runtime logs

    • Everything that happens when the container is started and your app code runs.
    • Framework messages from Gradio, Streamlit, FastAPI, etc.

You will normally see:

  1. Build logs when status is Building
  2. Runtime logs when status is Running or when a previous run crashed

3.2 Beginner way to read build logs

You do not need deep Linux knowledge. Focus on:

  1. Lines with ERROR or failed

    • For example:

      • ERROR: Could not find a version that satisfies the requirement ...
      • fatal: repository ... not found
      • Repository storage limit reached

  2. Typical beginner-visible build problems:

    • Bad requirements.txt

      • Pinned to versions that no longer exist
      • Typos in package names

    • Git repo too big or broken

      • Exceeding the Space Git 1 GB limit causes clone errors or “storage limit reached” during build.(Hugging Face)

If you see any of these, fix them locally:

  • Make sure pip install -r requirements.txt works in a clean virtual environment.
  • Remove large binary artifacts from the Space repo; put them in a separate model or dataset repo and download them at runtime instead.(Hugging Face)

Then push your changes again and restart.

3.3 Beginner way to read runtime logs

If build is ok and the Space starts then crashes:

  1. Open Runtime logs
  2. Scroll to the bottom and look for a Python traceback or clear error message.

Typical beginner mistakes from forum threads:(Hugging Face Forums)

  • ImportError (missing library)
  • Config file or model path not found
  • Trying to bind to localhost only instead of all interfaces
  • Out of memory when loading a very large model

Beginner-safe pattern:

  • If you see a Python error, try to reproduce it locally by running your app:

    • Install the same requirements.txt
    • Run python app.py or equivalent
    • Fix until it runs without crashing

  • Only then push back to the Space and rebuild.

4. Case 3: Space runs but shows errors in the UI or API

This is more normal application debugging.

Symptoms:

  • Status is Running
  • App page opens but some actions trigger errors
  • Or calling the Space as an API returns 4xx or 5xx with its own x-request-id(GitHub)

Beginner-safe loop:

  1. Open the app and trigger the failing action once.
  2. Immediately open Runtime logs and read the last lines.
  3. Fix input validation, missing files, or model download issues.
  4. Push small changes and test again.

In other words: treat it like normal Python or web debugging, but always check logs through the Spaces UI.

5. Safe things you can do from the UI, in order

Here is a simple sequence that is safe for beginners and covers many issues.

  1. Refresh and check banners and status

  2. Click Restart once

    • Observe whether status changes and whether logs update.

  3. Open Build logs

  4. Open Runtime logs

  5. If problem persists but logs make sense

    • Reproduce locally, simplify your app, then redeploy.

  6. If logs are empty or not loading and Space stays Paused or Building forever

  7. If still stuck and you only see a Root ID

    • Consider this infrastructure or moderation level.
    • Contact Hugging Face with Space URL, timestamps, and your Root=1-6938d880-3c2a37cf5f60af613ce8d7b0 so they can look into internal logs.(Hugging Face Forums)

6. If you want, we can apply this to your Space concretely

If you share:

  • Your Space URL, and
  • A screenshot or copy of the latest build or runtime logs

then I can walk through them line by line and map your case into the decision tree above.

Short summary

  • A paused Space that fails to restart and shows Root=1-... means the restart API hit an error. That ID is for Hugging Face engineers, not a direct error explanation.

  • First classify your situation:

    • Never leaves Paused with no new logs → likely infra or moderation.
    • Goes to Building then Error → build problem.
    • Runs and then crashes → runtime bug in your app.

  • Use the Space UI only: check banners, read build logs, read runtime logs, fix obvious errors, Factory reboot once, and toggle hardware.

  • If the Space remains paused or building with empty or missing logs and only shows a Root=... ID, treat it as a platform issue and contact Hugging Face with your Space URL, timestamps, and that Root ID.
