Hello,  
While monitoring the application we have observed an error, if we kept the GUI idle for a while 5 mins we have seen this **“Visualize:unknown error”**  
But this issue is seen only in **Microsoft Edge** , sometimes in **Mozilla Firefox** and never seen in **Chrome**.

Kibana version: **4.5**  
Elasticsearch version: **2.3**

Kibana 4.5 has already been EOLed ([EOL dates](https://www.elastic.co/support/eol)) so unfortunately we won't be looking into new bugs uncovered.

Microsoft Edge is also not in the [browser support matrix](https://www.elastic.co/support/matrix#matrix_browsers) for 4.x so some bugs are expected as we don't test with it.
