It says it needs nginx without apache - but how do i figure this out? if it my setup is different, should i change everything all together?

Please guide me how to install n8n. What do i need to do from my end?

So after i finished all the codes step by step, when i go to the subdomain where i intended to install n8n, it says an error saying it is a dangerous site with red background…
