SCCM 2012 R2 SUP Sync Error

Hi Guys,

My Primary software update point just started giving this error suddenly, it is running on Server 2008 R2, SUP ports are 80 and 443, nothing has changed but now when trying to run a Software Update sync, i get the following error in my wsyncmgr.log.

Sync failed: UssCommunicationError: WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.~~at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request). Source: Microsoft.SystemsManagementServer.SoftwareUpdatesManagement.WsusSyncAction.WSyncAction.SyncWSUS

I did recently add a downstream SUP role to one of my seconday sites which is running Server 2012 R2 if that helps.

Please could someone point me in the right direction.

Thanks

Leon

Hi,

No we are not using PKI, this was all working perfectly about 2 days ago.

Just started recently.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Hi,

I have attached the WCM.log from the primary SUP.

Could it be perhaps that the primary SUP is using ports 80 and 443 and the newly secondary site SUP being server 2012 R2 is using 8530 and 8531 ?

I would remove SUP at secondary and see it it resolves .

Please upload wsyncmgr.log and let us know if it syncs sometime?

Hi,

Apologies for the delayed reply but i have been traveling.

I checked the server again and the error was gone but i have the a timeout error now, i am busy cleaning up the WSUS DB to see if this will fix it, but my original question can be closed.

Thank you for the help and direction.
