I have a torrent with 2 trackers that are both "skipped" due to the lists in my settings files
Obviously "no host found" is a dead end.
but maybe, just maybe "connection refused" or "timeout" might be a temporary condition.
I'd suggest that when one goes to torrent properties -> trackers -> R.C. that this manual command override the skip list. Any auto announce should of course continue to be skipped, Allowing a one-time manual tracker check override would help without having to remove the tracker from the list (and readd it if it is still in failing condition)
