@stormi Could it be that there is any difference between the "netdata-ui" rpm package you provide and the official netdata rpm packages?
netdata-conf-1.23.2-1.el7.noarch
netdata-data-1.23.2-1.el7.noarch
netdata-1.23.2-1.el7.x86_64
Or could it be that it's related to XCP-NG 7.x? Because our cluster is still running 7.x ...
