WSUS stopped working

Hi Experts,

since some days my WSUS server is not running.
The service stopped after 5 minutes.

My server is a WIN2012R2 server with WSUS installed.
Some weeks ago all went fine.

Here is the error levent log:
The WSUS administration console was unable to connect to the WSUS Server via the remote API. 

Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.

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\.

I did it, but no success after the reboot.
The console comes up with Connection error.
Then I press Reset Server Node, and nothing happened.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Hi,

Go to IIS and check the WSUS Apppool status (under application pool). Is it started? if it's in stopped state, start it and try logging into WSUS.

This may also happen if the W3WP worker process and Windows Internal database is consuming more memory.

I found it, because in MAY 2016 there was an update and all WSUS server crashed in the world.

Did you check the health of your WSUS server with

wsusutil.exe checkhealth ?

After view the application event viewer.
