Strange thing is, from last month, I can sync with 2008RS server.
Anyway, I will not use it anymore, though.
WSUS Sync failure

WSUS 3.2.7600.226
WSUS sync has started to fail over the last few weeks, initially intermittentl, now I cannot get it to complete at all.
Update source is Microsoft
Console error: Unable to resolve the specified upstream server name.
“WebException: The request failed with HTTP status 404: Not Found.

This seems to be the key bit of the server log

So it is connecting to sws1.update.microsoft.com, and SSL validation succeeds. It fails after that with some proxy error.
(I realise that this server should be replaced, and work is in hand to migrate to Azure.)
Any help appreciated. Have been unable to fault the installation.
Thanks

Paul Kroitor 6 Reputation points2021-02-10T20:05:31.847+00:00 Does anyone know if simply disabling the WSUS service on SBS2011 works?
We have other WSUS servers; switching the workstations to use them would be straightforward, I imagine, but what about switching the SBS box itself over to a different update server?

If anyone has any intel, please share.

2021-09-22T23:01:59.8+00:00 I have this failure:

The last successful sync I saw was 4.56pm 20210921 AEST (UTC+10) first unsuccessful was 4.56pm 20210922 AEST
In UTC, that is the breakage happened sometime between 20210921 10:56 and 20210922 10:56.Nothing but failure since, and I have just now (20210922 23:04 UTC)tried a manual sync, which has failed
