SSH Authentication Issue: Permission Denied (Publickey)

Spaces
1

Hello Hugging Face Community,

I’m encountering an issue while attempting to connect to my Hugging Face Space via SSH. Despite following the setup instructions and ensuring my SSH key is uploaded, I receive the error:

Permission denied (publickey).

Steps I Have Taken:

  1. Generated SSH Key:

    • I created an ED25519 key pair using:
      ssh-keygen -t ed25519 -C "your.email@example.co"

  2. Uploaded Public Key:

    • I added my public key to the SSH Keys section of my Hugging Face account.

  3. Verified Key with SSH Agent:

    • Added the private key to my SSH agent using:
      ssh-add ~/.ssh/id_ed25519
    • Verified the key is loaded and matches the fingerprint.

  4. Configured SSH Client:

    • I created a configuration file at ~/.ssh/config with the following content:
      Host ssh.hf.space
    User <my-username>
    IdentityFile ~/.ssh/id_ed25519
    IdentitiesOnly yes

  5. Tested SSH Connection:

    • Ran the following command with verbose logging:
      ssh -vvv ssh.hf.space
    • Observed that the key is accepted by the server, but authentication fails with:
      Permission denied (publickey).

  6. Re-uploaded Key:

    • Deleted the existing key from my Hugging Face account and re-uploaded the same public key to ensure it’s correctly added.

  7. Verified Username:

    • Confirmed that my Hugging Face username is correct and matches the one I’m using in the SSH config.

Additional Details:

  • I am using OpenSSH for Windows, version 9.5p1.
  • My local SSH client can read the configuration file and correctly offers the key during authentication.

Request for Assistance:

I believe my public key is correctly configured locally and on the Hugging Face account, but I am still unable to authenticate. Could someone help me identify what might be going wrong? Is there something specific I need to verify on my Hugging Face account, or is there a known issue I may be missing?

Any guidance would be greatly appreciated!
