There are a few obvious things that can make libtorrent ignore the call to
force a tracker announce:

1. If the torrent is paused it will silently ignore it
2. If the tracker index is not -1 but still out of bounds in the tracker
list.
3. if the time you specify in the call is invalid and refers to a time far
into the future

To get a hint about what's going on, I would recommend querying the tracker
list periodically to see their status. The announce_entry includes the time
the next announce is scheduled for. Immediately after a force_announce
(with a time stamp of now or in the past) should be set to 1 second from
now.
