Same problem with sftp error. However, I get this error only on the Ubuntu server, which is under wsl2. If the main server is Ubuntu, everything is fine.

solution:

1. open ssh cfg:
   sudo nano /etc/ssh/sshd_config

2. uncomment "PermitRootLogin yes" (delete #)

3. set password for root:
   passwd root

4. authorization in the amnezia vpn program via root

In my opinion, this is a serious security issue. It's best to use a separate user and key instead of logging in as root on your server.
