It was running normally before, then suddenly disappeared, showing the Huggingface icon and a message saying “Building Space.”
I checked the backend logs, and before the logs stopped, there were several instances of “reloading database.” I tried restarting the Space, but it didn’t work. I tried rebuilding the Space, but it also didn’t work. Then I noticed my CPU is stuck in a spinning state. What should I do now?

The _cause is unknown and cannot be resolved by the user_ at this time.
The dirty but quickest workaround is as follows.
- Rename the current space to something appropriate and set it to Private (for safekeeping in case the issue is resolved in the future).
- Create a new space with an available name.
- Upload the same source code.

> Hi, this space ([MiniSearch - a Hugging Face Space by Felladrin](https://huggingface.co/spaces/Felladrin/MiniSearch)) was restarted today and got stuck in the “Building” state for hours. There are no logs indicating it’s actually building. Maybe it’s in some queue for building? But it never took so long. So I think there might be some error with the space. I already tried stopping, restarting and factory-rebuilding it, but nothing worked.

> A few of my Spaces have been “Building” for weeks. It’s happened in the past when it’s “Building” for a few days and then I reset it and its fine. But this time around it won’t start! I tried everything… restarting, factory rebuild, deleting files and then re-uploading, etc.

What a tragedy. From the posts you shared, I see many people are in the same situation. No idea how long it will take to recover. I even saw some people stuck on this issue for weeks…

Exactly. Even a Hugging Face staff member who was maintaining Spaces couldn’t solve the problem on his own… 🤢
It probably requires quite high-level permissions…

Me too. Python Gradio space. Was working fine yesterday. Committed modified app.py that works perfectly on my home PC in VS2022 . Even after factory rebuild, just sitting on “Building” while logs just look normal. Pushed and started.
EDIT: After about 1.5 hours this additional error message appeared int Build log following the normal messages that looked like everything was OK:
ERROR: failed to push spaces-registry.huggingface.tech/spaces/6801b2253a3d2135e30da61a:cpu-08475b3-7x848txl: unexpected status from HEAD request to [https://spaces-registry.huggingface.tech/v2/spaces/6801b2253a3d2135e30da61a/manifests/cpu-08475b3-7x848txl:](https://spaces-registry.huggingface.tech/v2/spaces/6801b2253a3d2135e30da61a/manifests/cpu-08475b3-7x848txl:) 401 Unauthorized

It must be an error for so many to suddenly appear at the same time… @meganariley @pierric @hysts

I finally created a new space, same configuration and same files as the space that was stuck building. It built and ran just fine. Deleted the stuck space.

I’m having the same issue. Stuck in building until I get a build error that says unexpected status from HEAD request

Suggests a problem with docker vs. AWS perms:
> “Today I stumbled upon the same issue. The docker buildx build … --push command failed with the same error message (unexpected status from HEAD request to : 403 Forbidden). But docker push was working uninterrupted. It turns out that buildix required one additional AWS ECR permission - ecr:BatchGetImage. 🙃”
I know nothing about this stuff, but hope that clue might help those who do 🙂

Same issue. Over the past 3-4 days, 2 of my spaces went offline due to “Build error”. They were working fine for the last 1 year.

Wow, you’re really having a rough time. Hope they can fix this error. I haven’t been using Huggingface for long, so I don’t have much data, and I had to rebuild after careful selection.

Was just having the same issue. What ended up working for me is to rebuild the image using a different Space Hardware. Then rebuild it back to the original hardware.

The infra team has resolved the issue. We are still investigating the root cause, but restarting the Space should fix it.
