Hi all! I'm new on linux.
I'm learning this tutorial https://docs.microsoft.com/en-US/asp...aspnetcore-2.1

I need Host my Web Application ASP.NET Core on my CentOS with Nginx

I followed the steps but I have a problem status kestrel-helloapp.service is*activating

Why this service not complete to activate?

ERROR:"activating"

Did the nginx run without the aps.net core config?
Does /var/log/nginx give any idea on what might be happening?
