what exception can I use for general network problems?
<p>In my case server is not available and so I can not read data for client and so I want to throw an Exception.
What Exception should I throw?
I don't want to create my own exception class for such situation, because there are a lot of different situations in program.</p>

<p>Probably there are some kind of "general" exception, like "NetworkProblem" or even just "Problem" or something?</p>

<p>I don't need anything specific, just an exception with message.</p>
