PENDINGMECM WSUS sync not working.

[scalyback]

All of a sudden our SCCM server on a disconnected network has decided to just not sync anymore, no idea why it has happened no changes have been made but from a bit of googling I found this in the wsyncmgr.log
Sync failed: The operation has timed out. Source: Microsoft.UpdateServices.Internal.DatabaseAccess.ApiRemotingCompressionProxy.GetWebResponse

In the Component Status for SMS_WSUS_SYNC_MANAGER:
WSUS Synchronization failed.
Message: UssInternalError: InvalidOperationException: .
Source: Microsoft.SystemsManagementServer.SoftwareUpdatesManagement.WsusSyncAction.WSyncAction.SyncWSUS.
The operating system reported error 2147500037: Unspecified error

It's quite annoying as this was working just fine in the middle of July but now nope July & August updates are either not downloading for July when I create my Software Update Group or as in August updates I run my monthly robocopy to put them on the SCCM Server, run the wsusimport and the next day sync the updates and that is where it is now all going wrong.

Any help would be gratefully received.

Did you check with the network team to see if there were any changes made to the firewall? From the log entries, it's not very clear why this error is occurring.

Unfortunately for me I am the network team as well, I have made no changes , think it might just be a glitch that will need removal of the SUP and re-installing the SUP
