This error is typically caused by a problem on the World Community Grid servers, often as a result of maintenance.
For BOINC 5.10 and earlier, this is a permanent failure (the result will be marked as an error). For later versions this is a transient failure, and BOINC will attempt the upload again.
No action is required.
