The OpenConnect project seems to be reporting that the download has been failing for the last year.
Unfortunately it doesn't actually give any details of what went wrong. There's no error reported at all, as far as I can tell; just "failed".
I tried adding the same git repository URL again (before reading the comment asking me not to delete and recreate it; sorry), and on the server I see a connection from lb1.blackducksoftware.com. which appears to be correctly downloading:

(Timestamps are GMT-4).
Rescheduled the stalled update which finished OK (402 added commits). Analysis page is now at Jun 20 2012 and last commit is at 2012-06-19 (about 16 hours ago).
Please remind me here if the project stalls again.
