SCCM 2103 error 6703 after enable upgrade feature windows 10

Question

Dear All,

I search many about this issue, I found with my SCCM server that when I enable checked box "Upgrade" in Classifications then cannot sync and have issue 6703 as below. I tested when I drop check box "Upgrade" then it syncing ok. Do you have solution for me?

Sync failed: The operation has timed out. Source: Microsoft.UpdateServices.Internal.DatabaseAccess.ApiRemotingCompressionProxy.GetWebResponse

2. Unchecked box "Upgrade" in Classifications
3. Checked box WSUS maintenance as recommend of SCCM 2103
   
4. Sync update ok ( will sync update, delete obsoleted/decline update, Reindex WSUS DB)
5. Checked box ''Upgrade' in Classifications again
6. Sync again and everything ok to now.

Hi @Hoang Van Minh ,

Based on the operation timed out messages, it should be some kind of network issue or security software/appliance in place that only intermittently kicks in.

Maybe you've got a proxy configured or a network security device that requires authentication? If there is no proxy between them, we could try to uncheck the classifications and products, resync to check if it is normal. And then select check the box "Upgrade" in Classifications, select products, for example, windows 10 to check if the problem is solved.
