Nextcloud installed, but unavailable

Hi all,

i installed yesterday on my new oDroid C2 DietPi and some optimized Software including Nextcloud, Lightpd, PiHole, Certbot and Fail2Ban.
Now my Problem is that i can’t reach my nextcloud. PiHole and my Website are avaiable, but if i want to acces nextcloud via mydomain.ddns.de/nextcloud or 192.168.1.1/nextcloud my browser says, this site is unavailable. If i do the same Thing on my PineA64 everything works but i use this one for other stuff.
Does anyone know why i cant reach the my Cloud?

Sincerly,
Birneklub9
