Authentication Error When Pushing Code to New Space

Issue: I am unable to push to newely created space. OS: Windows 11

I have created a space here git@hf.co:spaces/dennisnlt/mcp-sentiment. I have added the appropriate ssh keys to my account.

I have verified the following step and correctly receive my username:

command “ssh -T git@hf.co” Hi dennisnlt, welcome to Hugging Face.

GIT CONFIG: [core] repositoryformatversion = 0 filemode = false bare = false logallrefupdates = true symlinks = false ignorecase = true [remote “origin”] url = git@hf.co:spaces/dennisnlt/mcp-sentiment fetch = +refs/heads/:refs/remotes/origin/ [branch “main”] remote = origin merge = refs/heads/main vscode-merge-base = origin/main

Error from “git push”:

** WARNING: connection is not using a post-quantum key exchange algorithm. ** This session may be vulnerable to “store now, decrypt later” attacks. ** The server may need to be upgraded.

Please make sure you have the correct access rights and the repository exists.

Any help would be greatly appreciated.

Update

Apparently git on windows can use its own ssh…

Fix ( Force Git to use the Windows system client ): git config --global core.sshCommand “C:/Windows/System32/OpenSSH/ssh.exe”
