closed connection...?

Helo colleagues @moon...
   what kind of reasons there are for "closed connection" to <moon>-server?
I liked to work over the weekend, but unfortunately, the server gives
statements only that he closed the connection...
   Can I make my working time table more detailed with new "opening"
schedule???
   Thanks a lot for replying in advance,
