Data feed just stops working

 
My apologies for this simple question from someone new to this piece of SW.

I have excellent internet connections and no problems with them.

But, the MetaTrader tool, after a while, just stops updating the charts. Nothing I can do seems to bring it alive again. When I refresh a chart the log says that data has been downloaded, so the server seems to be serving. But the tool is no longer working with realtime data.

Is there any kind of indicator, other than the fairly useless Connection Status indicator, that says what is going on between the server and the client?? And what the client thinks is happening?

Since I have no idea what broke, I don't know how to try to repair it. :)

Many thanks for the help and apologies again if this is operator error.
 
Wait for Monday.
