No connectivity with any of Web Conferencing Edge Servers. External Lync clients cannot use Web Conferencing modality. RRS feed

  • Question

  • I've been battling this for sometime now.  All certificates, etc.. are in place and valid.  Each Web App Server is setup as it should be, but shows 'Unhealthy'.  I can upload a PowerPoint to users within our network, but I can't share with external users that are on the same domain.

  • Hi,

    Please specify the term "external users on the same domain". As for external users(not your domain users), you need to deploy Reverse Proxy and for internal users (connecting from home/internet), you need Edge server.

  • Hi ScoobyDoo,

    Where did you find it show “unhealthy”? please give us an snapshot about “unhealthy”.

    In addition to above suggestions, we should publish office web application or office online server to Internet if we want to share PPT with external user:

    https://technet.microsoft.com/en-us/library/mt297723.aspx

    “Configure access for external users

    If you want external users (that is, users logging on from outside your organization’s firewall) to have access to Office Web Apps Server PowerPoint presentations, then you will need to use Office Web Apps Server and a reverse proxy server. You will also need to create and configure a website publishing rule, which will help ensure that users are able to connect to the server”

  • Issue:

    External users are unable to view a PowerPoint presentation that has been uploaded by an internal user. 

    Symptoms:

    HQLYNCFE01: Event ID 41026 No connectivity with any of the Web Conferencing Edge Servers.  External Lync clients cannot use Web Conferencing modality.

    Event ID 36887 A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 48.  This alert is generated every minute

    HQWA01:  Event ID 1004/2004 <?xml version="1.0" encoding="utf-16"?><HealthReport xmlns:xsd="

      <HealthMessage>AgentManagerWatchdog reported status for AgentManagerWatchdog in category 'Recent Watchdog Reports'. Reported status: Machine health is Unhealthy</HealthMessage>

    </HealthReport>

    When running ‘Get-OfficeWebAppsMachine’ from powershell, the status is ‘Unhealthy’

    HQLYNCEDGE01:              Event ID 14603 The following discovered partners are sending frequent invalid SIP requests to the Access Edge Server.

    Troubleshooting Steps:

    1. Check all certificates on all servers.  This includes public, and internal.  Re-keyed certificates to ensure that everything was accurate.  Worked with Microsoft directly to ensure this was done properly.
    2. Completely re-installed both HQWAS01 and ARWAS01 and created new Office Web App Farms as per Microsoft documentation.
    3. Confirmed that Reverse Proxy Server Farm exists and is online
    4. Repaired Lync Server Core Components on both HQLYNCFE01 and HQLYNCEDGE01
    5. Checked Cisco ASA firewall NAT rules
    6. Checked Cisco ASA Access List rules
    7. Checked Microsoft firewall rules on HQLYNCFE01 and HQLYNCEDGE01
    8. Ran Port Tester on both HQLYNCFE01 and HQLYNCEDGE01.  Everything seems to check out.

  • Hi ScooboDoo,

    To this issue, we suggest you use Skype for business web app in internal organization to check if you could see PPT in Skype for business web app. For external user, try to use the different browsers to check if the issue persist.

  • Hi There

    If this started recently after OS updates and that event occurs every min almost then see below for the 2 workarounds. 1st workaround will take the most time, but 2nd workaround is a registry entry and restart of the webconferecing service - only need to apply on frontend servers.
