If you receive the error: Could not load host key: /etc/ssh/ssh_host_ed25519_key in your SSHD service, this is because you have enabled the ed25519 HostKey in your sshd_config file and the host key cannot be created for some reason.
To generate the Host Key, it will be sufficient to use the following command. Afterwards the problem will be solved.
ssh-keygen -A
