WSUS administration console error

Hi everybody. I have problem with my WSUS server. It is my downstream WSUS server. WSUS VM parameters 4 CPU and 16 GB RAM. Please help to resolve this problem.


The WSUS administration console has encountered an unexpected error. This may be a transient error; try restarting the administration console. If this error persists,

Try removing the persisted preferences for the console by deleting the wsus file under %appdata%\Microsoft\MMC.


System.Net.Sockets.SocketException -- No such host is known

Hello Vusal,


Thank you for posting on Q&A.


I found the following description of this error:
https://docs.microsoft.com/en-us/troubleshoot/mem/configmgr/wsus-console-crashes


Perhaps we could try to maintenance the WSUS. We could refer to the below link to maintenance the WSUS Server:
https://docs.microsoft.com/en-us/troubleshoot/mem/configmgr/windows-server-update-services-best-practices


If there are updates about this issue, please keep us in touch.


Regards,
Rita

Are you performing the proper WSUS maintenance including but not limited to running the Server Cleanup Wizard (SCW), declining superseded updates, running the SQL Indexing script, etc.?

i cannot sign in wsus console and therefore i cannot use options. I deploy this downstream WSUS 2 days ago. What is the cause i don't know

Thanks but doesn't work..
Following should works..
It turns out to be a private memory issue in the WsusPool which seems to be depleted quickly. It is possible to assign more memory, but since I have no clue how much memory to assign I changed the setting to ‘0’ (1,843,200 KB is default) so the WsusPool can use anything it needs.

Are you performing them at the upstream? Have you tried restarting the downstream server? Have you run the SQL Indexing script? Both of those don't require WSUS to be working.

İ restart downstream server but not performing maintenance which you say in downstream and upstream server and not performing SQL indexing script.

Is the WSUS server is configured with ssl?
From the log itself, seems as dns issue....

Also - is the WSUS is installed with windows IIS? is it ok? well configured?

Is the downstream server is brand new? is the post installation tasks were completed?
Some of these errors occur when the default web site is disabled within the installation process (might be relevant also after the installation is completed - did'nt happen for me, but...)
