Checking the /etc/nginx/keys for spws.cert file and there is no files in the /etc/nginx/keys folder!

The /ect/nginx/conf.d/ has a byo.conf file so something is getting correct during storage setup and config via the Web GUI.

For some reason the spws.cert and spws.key files are not created?

Any ideeas why?
