 *

/*! \brief Could not connect.
 * 
 * The socket could not connect to the IRC server, or to the destination DCC

 *

 * Second reason is that the command queue (which keeps command ready to be 
 * sent to the IRC server) is full, and could not accept more commands yet.
 * In this case you should just wait, and repeat the command later.
