Connection Failed When Using ED25519-SK

Core Tunnel Ask for Support
1

Is it supported to use Core tunnel with ED25519-SK ssh key? After I input the pin, I got error Permission denied (publickey).
I can connect to the server normally when using Mac Terminal.

Here is the error log message:

07:15:38 Connecting...

Are you using Core Tunnel from App Store? If yes, please using Codinn Store version of Core Tunnel instead.

No, I am using Core Tunnel from direct download from here:
https://codinn.com/download/Core%20Tunnel-latest.dmg

Anyway, it just ask to input pin, after I input pin it should ask me to touch the yubikey before giving access but instead it just denied it.

Sorry for late reply, I'll investigate this issue.
