ssh still works OK, but each time it prompts you to accept the host you are connecting to:
Could not create directory '/home/myuser/.ssh'.Reason is that ssh does not find your home directory. Easiest solution is to point it to your windows home directory. To do this, add this line to your_cygwin_install_dir\etc\nsswitch.conf file:
The authenticity of host 'myserver (168.250.1.174)' can't be established.
ECDSA key fingerprint is SHA256:eSpqYAq2c7k843RfqpbpvK9F118XsKCArBdBheRN8c0.
Are you sure you want to continue connecting (yes/no)?
