I'm running Zimbra_607_341 on vSphere 4, and checks for updates. Is there any updates for ZCA 607? Does it fail for anyone else?

The "Last Install" message says "Failed to install updates (Update manifest not downloaded. Please try to download again. ) on ..."

From the SSH shell, I can speak to the default update URL:

root@zimbra:/opt/zimbra/log# nc files.zimbra.com 80
GET /zca/updates/ HTTP/1.1
Host: files.zimbra.com

I have made a few changes to the ZCA installation:
* Disabled the Ubuntu firewall
* Disabled the redolog archive with zimbraRedoLogDeleteOnRollover: TRUE
