Skype for Business Screen Sharing Session Disconnected RRS feed

  • Question

  • We had a report of a Skype for Business Meeting Screen Sharing session being disconnected a few times in the same session. We have a hybrid environment and all of our meeting organisers are homed online.

    Looking at the logs I can see there are a few errors:. 

    1st error

    ms-diagnostics: 2044;reason="Publication version out of date";

    - <Fault>
           <Faultcode>Client.BadCall.WrongDelta</Faultcode>
        +  <details>
     </Fault>


    2nd error

    ms-diagnostics: 4154;reason="Endpoint is not currently registered and a re-registration required for this operation.";HRESULT="0xC3EE79F9(ES_E_CLIENT_REGISTRATION_REQUIRED)";

    3rd error

    ms-diagnostics: 3041;reason="Participant is not connected to conference";

  • There will be 2 possibilities why the session is getting disconnected...

    1. The Skype for Business client version is running under lower version which may some known issues.

    >> Get the Client version to latest available version.

    2. Packet drops during screen sharing in conference.

    >>Capture the network logs (Netmon/Wireshark) and see the TCP high rage ports traffic ; if it is using RDP protocol to share the screen

    >>Capture the network logs (Netmon/Wireshark) and see the TCP high rage ports traffic ; if it is using VbSS protocol to share the screen

    If you see packet drops, get it fixed at network layer..

    Also, in client UCCAPI logs, you must be seeing the BYE packet for Screen sharing dialogue, what do you see in it ?

  • Hi Blue_Craig,

    Agree with Neeranjan Shettar. You could update the SFB client to the latest version, and check the high rage ports traffic in your environment.

    In addition, you could also refer to Office 365 URLs and IP address ranges, It states that the endpoints in the Skype for Business Online FQDN and IP address are reachable. 


    Best Regards,

  • We have patched the workstation, so hopefully that will help.
