In VPS 2, the "info" message you are getting is just because you don't have any user created for HTTP Authentication, so you can not access admin pages, like phpMyAdmin, etc. Use sudo httpauth -add to create a user if needed.
In VPS 1, it means that SWAP file/partition was not found. Webinoly always try to create it when NGINX is installed, this error is either because Webinoly fails to create it or you remove it.
