I have had L4 open most of the day and a few minutes ago I changed a layout and the sync process started then I got the little yellow triangle. Looking at the L4 log I see the following :
2010-07-08 13:04:02.8544 9 Warn SyncManager Error occurred during synchronization upload - Libronix.DigitalLibrary.Synchronization.SyncClientException: Not Found ---> System.Net.WebException: The remote server returned an error: (404) Not Found.

at Libronix.DigitalLibrary.Synchronization.SyncManager.TryUploadItems(ISyncClient syncClient, IDictionary`2 dictItemSources, List`1 listSuccessfulBatchSyncDates)
Is this a problem with the server or something my end? My internet connection is working fine and the program appears to working fine.
