Can't get no-touch-required to work

[knsonier]

I have v9.1.0.0p1-Beta installed on a Windows 10 machine and generated a key with the command:
ssh-keygen -t ed25519-sk -O no-touch-required -O verify-required -f my-key

I added the pub key to my authorized_keys file on my Linux server with the no-touch-required option and tried to ssh from Windows with this being the result:
sign_and_send_pubkey: signing failed for ED25519-SK "my-key": requested feature not supported

I then tried to use the key from another Linux machine and I can ssh into the server without any problem so I'm a little bit confused. I can generate a working key with no-touch-required on Windows 10 but I can't actually use it? Google hasn't been very helpful at trying to solve my problem so I'm hoping someone here can help. I hope this made sense...

Thank you for your help!

Facing the exact same issue here, I can create the key but I can't use it.

On the server you are trying to connect to (the Linux host), do you have the option "no-touch-required" specified before and on the same line as your public key in ~/.ssh/authorized_keys? sshd's default behaviour is to reject no-touch-required keys.

Yes, I had that setting in the authorized_keys file on the same line as the pub key.
