nginx not redirecting localy but ok from other networks – Debian

i am having troubles with nginx. The problem is that when i access mywebpage.org from the phone or laptop over data connection or on friends wifi it works. But if i try to access it over wifi or my cable connection on the same home network it loads for few minutes (After few minutes some errors appears in the console).

It should redirect me to my home ip 192.168.1.100:2000 where i have my nextcloud. After a while logo of nextcloud appears but it doesn’t progress. If i press F12 and see Sources i can see that the browser gets something like favicon css and more. But the site only loads for few minutes.

Description of my system

I have Debian server installed where i have open media vault, Nextcloud and Home Assistant. The nginx was automatically installed with OMV. I tried to use Nginx Proxy manager installed via portainer but he did the same thing. I am not using HTTPS in this setup.

after few minutes there are this errors in the console of the browser.
