SCCM 1702 Updates not coming through

Question

I am currently experiancing an issue with my SCCM server not recieving the updates from microsofts server and when I check dmpdownloader.log I see

ERROR: Failed to download Admin UI content payload with exception: The request was aborted: Could not create SSL/TLS secure channel.
Failed to call AdminUIContentDownload. error = Error -2146233079
ERROR: GetSccmConnectedServiceUrl Exception System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.~~ at System.Net.HttpWebRequest.GetResponse()~~ at Microsoft.ConfigurationManager.DmpConnector.Connector.SCCMConnectorUtility.GetSccmConnectedServiceUrl(IWebProxy prx)

There is no proxy in the way or firewall that would block these sites at all I can access them through Internet explorer on the server and from other machines on the network I have tried everything that I can think of any advice is greatly appreciated

Hi, @Ryan Elliott

Thank you for posting in Microsoft Q&A forum.

This issue might occurs when the Baltimore CyberTrust Root certificate is missing, expired, or corrupted.
You may check your Baltimore CyberTrust Root under Trusted Root Certificate Authority.

Hi there,

Beginning with Configuration Manager current branch version 1702, clients use boundary groups to find a new software update point, and to fallback and find a new software update point if their current one is no longer accessible. If you install a new site that runs version 1702 or later, you must assign software update points to a boundary group before clients can find and use them.

Configuration Manager clients don't get software updates https://learn.microsoft.com/en-us/troubleshoot/mem/configmgr/clients-not-get-software-updates

Also check if the required ports are opened https://learn.microsoft.com/en-us/mem/configmgr/core/plan-design/hierarchy/ports

Btw 1702 is a really old version, you should upgrade to a newer version too.
