After apply KB 4470124 - front end did not start RRS feed

  • Question

  • Hi everyone

    I deployed Skype for business server 2019 standard a few weeks ago.  It was operating quite well with 10 users.

    On windows maintenance I performed the following administrative tasks:

    - Applied windows updates and sql 2016 updates till build number version 13.2.5102.14

    - Apply the March 2020 update to skype, Updates for Skype for Business Server 2019

    https://support.microsoft.com/en-us/help/4470124/updates-for-skype-for-business-server-2019- Restarted the Skype server and noticed that Sql automatic services tookt start automatically

    After waiting for several minutes, all Skype  services  except the front end service started
    In this scenario, I applied this url:


    and found this error:

    Error: An error occurred: "Microsoft.Rtc.Common.Data.SqlConnectionException" "Could not connect to SQL server after 3 retries. Reason: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - The remote computer refused the network connection.)

    Connection String: Data Source=(local)\rtclocal;Initial Catalog=xds;Integrated Security=True;Application Name=Microsoft.Rtc.Management;Connection Timeout=60

    I could get all group in the login

    Could anyone give any additional advice to fix this issue?

    Warm regards MeVs
