When current console deployed on latest ispn server, the Global Statistics page is showing error (see attachment). But the interesting thing is that sometimes it is loaded properly (see 2nd screenshot).

I thought that it depends on the user, but it just loaded normally randomly and more often shows error.

UPDATE:

Seems that the issue comes from the server and not from UI.

If you start the server, type in the browser this url: http://localhost:11222/rest/v2/cache-managers/default/stats and enter username/password (e.g. admin), it will respond with this error message (see attachment). So UI just shows what it gets from the server.
