Kiali Version 1.84 caused issue in Traffic graph

[preshit1505]

Describe the bug

We have recently upgraded the kiali version to 1.84 after I opened a issue of not able to see the trace details/span tab. But now we are seeing a different issue i.e. traffic graph is showing error "Cannot load the graph: K8s Cache [bdrck-preview-ctrlpln] is not found or is not accessible for Kiali" once we increasing the time duration in the tab.

So we have two environments one is preview and other is Live. We have never experienced seeing this error before as in a live environment we do see preview env's istio NS graph and vice-versa.

Expected Behavior

once we downgrade the version back to 1.81, i dont see the issue anymore.

Once we downgrade,

What are the steps to reproduce this bug?

1. Version upgrade to 1.84
   2 increase the time duration to more than 2m in traffic graph tab

@nrfox yes Nick, seems like its a similar kind of error. Do we have any update on that then? Can we resolve this with any configuration change?
