Hello guys! I have a Debian 8 server running Nginx, PHP7 and ISPConfig. Everything was working perfectly, but I entered the reboot command on the server, and now I can not access the ISPConfig panel and all the sites are offline. When accessing the panel URL, the error appears: "ERR_CONNECTION_REFUSED" (in Google Chrome) I'm a beginner, so I'm grateful if you can help.
Resolved! It was Apache2 that was running. I disabled it and restarted Nginx and it all worked again.
