Me too.
Consistently.
This is on a VMware installation of Ubuntu. A brand new install of Ubuntu Server 16.04.02, and after installing easy engine, and attempting to create a new site, I get those same errors:
ee site create siteexample.com
Running pre-update checks, please wait...
Setting up NGINX configuration [Done]
Setting up webroot [Done]
Reload : nginx [Failed]
Oops Something went wrong !!
Calling cleanup actions ...
Reload : nginx [OK]
service nginx reload failed. check issues with nginx -t
command.
Check logs for reason tail /var/log/ee/ee.log
& Try Again!!!
Trying to do a manual
device nginx reload
works fine. No error.
It seems others are having this problem, but there are no real answers.
