Problem with Letsencrypt on Raspberry

Hi guys, I have a problem with Let’s Encrypt.
I installed ncp on my Raspberry Pi 3, but when I try to activate the SSL with Let’s Encrypt nothing happens and I am forced to turn off the Raspberry to enter the ncp panel again. Can someone help me?

Someone might be able to help, if and when you provide some information on your setup, output of logs, etc.
Do you have a screen and keyboard attached to your rpi or ssh enabled?
If so, use pastebin or similar to post a link to output of

sudo ncp-report
