Result: It is redirected to the Plone page .. where it say's "... Plone is up and running ..." where I can create a new Plone site. I have created a new site: site1
Question: how do I need to modify the path so it points directly to the "index" page and NOT to the config page.
using the suggestion - how to config ngix I always have in the URL the IP instead of the Domain. How can I solve this?
I don't think the config is used at all, as you see an IP address in the links in the output.
Make sure the config is correct (nginx -t or nginx -T) and that nginx is restarted.
Check your logfiles to see of your requests are coming in there at all.
