WSUS Console keep crashing

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.

    Thanks for your posting on Q&A.

    In my opinion, there are several reasons may cause this error. It means that the WSUS console did not connect to the WSUS server right now.

    Perhaps we could try to follow the below steps to see whether this issue will be resolved or not:

    • Make sure the following services running



    IIS site:



    Hope the above will be helpful. If there are any feedback, please remember to inform me in time.

    The way I fixed this problem: open CMD as admin, go to C:\Program Files\Update Services\Tools then run following command wsusutil.exe usecustomwebsite true

    Hello Lalajee

    Changing private memory to 0 will completely disable the app pool recycling and will not fix this issue. Please change the value incrementarlly, sometimes even triple the amount of the initial value in order to handle the data.

    This condition may happen also due to a "dirty" database. Please run a maintenance on the Server:

    And, of course, it is assumed that you have already restarted your IIS and SQL servers, of course

    There's much more to the monthly maintenance than running the SQL Script. Are you performing the proper WSUS maintenance including but not limited to running the Server Cleanup Wizard (SCW), declining superseded updates, etc.?

    Map a drive to the server(s) you need to connect to using an account created and given WSUS Admin access. Then connect to the WSUS server with the Admin console.
