PR4100 dashboard timeout after 30 sec

I purchased an 8TB PR4100, loaded my 5 shares and files, then updated to the latest firmware (2.31.149). I now get a dashboard login timeout after about 30 seconds. Changes I make while in dashboard stick, but the 30 second timeout makes work difficult! I tried opening on Chrome and Opera but the timeout is always the same.

Hi,
You can try 40 second Reset to overcome on this issue. Please refer the below mentioned KBA-
