We've suddenly got a problem with our dashboards on SDP, they've stopped loading since last week, we simply get a screen with the four grey bouncy loading bars. Everything else on the system seems to be working OK.

We're on 14304, there are no errors in the system log. the only issue we had this week was that mail send failed because we'd forgotten to update our App registration in Azure (now fixed and I can't see how it could have affected this). We've restarted the service and the server as a whole without changing anything.
