If you mean you cannot upload to main CS (=Collection Server 171.54.65.58) ?... from your fah log you could check where it tries to upload ...
...then you could continue to check from this page about condition of the servers. See... main cs is on Reject Mode and it has been already noticed at official forums. But it's weekend.
Just left f@h on, it tries to upload finished wus periodically. When main CS is up again... wus will go through Maybe tomorrow...
