Unable to download PowerPoint slides - Lync 2013

Hi there,

Anyone have seen issue were clients are unable to get the shared PowerPoint slides. If I look the client log I can find the following line:

<diagHeader>54005;reason="A resource was unable to be downloaded via HTTP";ClientType=Lync;Build=4.0.7577.4456;Branch=lcs_se_w14_main;ContentMCU="sip:userA@company.com;gruu;opaque=app:conf:data-conf:id:K12345GW";ConferenceUri="sip:userA@company.com;gruu;opaque=app:conf:focus:id:K12345GW";HTTPError="200";HRESULT="0x80072EFF";IISUrl="https://lyncFE1Web.domain.local/CollabContent/{12AB12AB-A15D-1234-1234-380AB93A574B}/k12345gw/12345678-0001-0005-f7a4-5e2a36e3d9a2.bin"</diagHeader>

When I'm looking for this on the IIS I can see the following line:
2015-08-18 07:00:51 10.20.30.40 GET /CollabContent/{12AB12AB-A15D-1234-1234-380AB93A574B}/k12345gw/12345678-0001-0005-f7a4-5e2a36e3d9a2.bin - 443 - 10.152.99.40 Mozilla/4.0+(compatible+;+MSIE+9.11.9600.17914+;+Microsoft+Windows+7+Professional+Service+Pack+1+;+Placeware+RPC+1.0) - 200 0 64 4372

So IIS does not see any trouble, but client obviously is failing.

Does anybody knows what the error code "54005" means, or is it only a general i

We do, but that URL is excluded (*.domain.local) from the proxy. And of course this is not continues problem.

Hi Petrix,

You can try to reinstall the repair the IIS URL Rewrite Module 2.
Go to control panel on each front end server and repair the IIS URL Rewrite Module 2. 
Let me  know if this work please.

Regards!

Hi Petri X,

 

Please try running the following command and then reboot Office Web Apps server.

Set-OfficeWebAppsFarm allowhttp

 

It seems the client cannot access WAC Server via Http.


 

Best regards,

Eric
