Can't use netdata


I have a question, I have installed openwrt to mi router ac2100 and then through opkg installer I installed luci and netdata. Now when I try to reach netdata through , either I cant connect at all or I get lots of errors such as "ERROR 405: Cannot download charts index from server" "Cannot load required JS library".

I made clean firmware reinstallation and I only installed luci and netdata afterwards but no solution.
