Office web App Server Not Working Properly

Hello Everyone,
We have published Office Web Apps server externally through reverse proxy and it has some issues. Now if we browse the link
https://owas.schs.sharjah.ae/hosting/discovery (Internally) or
https://owa.schs.sharjah.ae/hosting/discovery (Externally) I get the XML Page.
Now when I try to browse any other pages in the directory for example
https://owa.schs.sharjah.ae/op/generate.aspx or another Url like
https://owa.schs.sharjah.ae/m/Presenter.aspx whether it is browsed internally and externally I get the error file not found '404' but the files do exist in the directory.
No idea on how to solve this issue, any help on this matter is really appreciated.
Regards,
Sheldon

What specific issue are you having?
Are you wanting to use the WAC to open files using the URL? If so, have you set OpenFromUrlEnabled to true? You can
check this using Get-OfficeWebAppsFarm cmdlet and Set-OfficeWebAppsFarm OpenFromUrlEnabled $true cmdlet.
I have several Office WebApp instances that I've deployed for Lync PowerPoint sharing where the setting is not enabled and I am also unable to browse to those pages, but PowerPoint sharing works fine.

Office Web Apps server not working externally

Hopefully someone with a functional OWA server can help. When my users try to share a presentation, whiteboard, or poll as an external user or to an external user (coming through Edge), the content fails to share and this error occurs:
"We can't connect to the server for presenting right now"
The server functions internally fine and content shares perfectly. The OWA server has a certificate from an internal CA and it is published through a TMG reverse proxy. When I hit the discovery URL, it works fine and triggers the reverse proxy
rule. However, when I try to share content, it does not hit the rule.
Thanks for your help!
Jim

Hi,
Looks like the external lync clients can't connect the office web app server. So please check if you publish the web office app to internet correctly.
Please refer this document about Publishing Office Web Apps Server Using a Reverse Proxy Server:

Will Office Web Apps Server 2013 work with SharePoint 2013 sites hosted in SP2010 compatibility mode?

We are planning a upgrade of a SP2010 farm to 2013. There has been a bit of customization so we wish to run the old sites on the new SP2013 platform in SP2010 compatibility mode.
So my question is will Office Web Apps Server 2013 work with the old sites hosted in compatibility mode?
I found a similar query from March 2014 found here
http://sharepoint.stackexchange.com/questions/93101/office-web-apps-2010-running-on-sharepoint-2013-for-compatibility-mode-sites/116281#116281
Has there been an update released to resolve this
Cheers D

Hi ,
According to your description, my understanding is that you need to know whether Office Web Apps 2013 is working with SharePoint 2013 sites which is in SharePoint 2010 compatibility mode.
For my test, Office Web Apps 2013 with SharePoint 2013 sites which is in SharePoint 2010 compatibility mode is working fine.

Office Web Apps is not working

Hi,
We have tried to deploy Office Web Apps Server but, after a number of tests, we haven't been able to view PowerPoint presentations. We tested "everything" but it didn't work.
Finally, to simplify and focus the problem, we just deployed Office Web Apps Server "on its own", that is: just Internal URL, HTTP, Open From URL Enabled and sharing docs from a shared folder in the same server. So we have:
\\wacserver\share\<Docs> (Excel, Word and PowerPoint)
http://wacserver
They work both "/hosting/discovery" and "/op/generate.aspx".
If we try to view Excel doc, it works. If we try to view Word or PowerPoint, id doesn't work.
For PowerPoint, it appears the PowerPoint Web Apps frame (FILE, START SLIDE SHOW, SLIDE - OF -, NOTES...) and, in the center, an animation
"PowerPoint Web App .....". After a couple of minutes, it stops with "Either you've lost network connectivity or our server is to busy to handle your request".
What we have seen from different sources:

but SYSTEM, we have checked, has "Full control" permissions in those keys or folders.
These errors appear by Office Web Server running itself, although we are not making a PowrPoint file request.

pid).
We have tried a number of things but none has worked. The farm has just one server and it says ist's unhealthy. We have Windows Server 2008 R2 SP1. We have read some ways to fix the health, like HTTP Activation feature, but it only works
for Windows Server 2012 as fas as we know.
Has anybody experienced something like this or have a posible solution? Office Web Apps Server should be so easy to deploy but we have spent a lot of time with this.
Thank you very much. Your help will be very appreciated.
Kind regards.

Hi John,
According to your description, my understanding is that you cannot view the PowerPoint files in Office Web Apps in SharePoint.
Was there any error when you view the PowerPoint files in Office Web Apps?
You can troubleshoot the error following the link below:
http://technet.microsoft.com/en-us/library/ff431687.aspx#tshoot
I also recommend to re-configure SharePoint to use the Office Web Apps Server to see if the issue still occurs.

Office web apps feature not working after setup and configuration?

Hi I have installed the SP1 update and since then my office web apps features are not coming up in SharePoint. After running the updates and attaching the farm back i see the bindings and settings are applied but somehow the office web apps features are
not coming up in SharePoint. Can someone let me know what might be the issue?

Did you delete and recreate the WAC farm after you updated?

Office web apps "Server error in '/wv' Application"

Hi, I successfully installed office web app for sharepoint 2013. However, when I tried to open documents, it shows the preview but once view/edit in browser, I got this error. What seems to be the problem?
Server error in '/wv' Application.
Unable to determine zone from request

Hi ,
According to your description, my understanding is that you encountered the error “Server error in '/wv' Application. Unable to determine zone from request” when you open document using Office Web Apps.
Are you using https:// to access the Office Web Apps server? Is the default zone of your web application in Alternate Access Mappings using http:// ?
If so, you can change the default zone
of your web application in Alternate Access Mappings to use https:// .
Or set AllowOAuthOverHttp to true:
$config = (Get-SPSecurityTokenServiceConfig)
$config.AllowOAuthOverHttp = $true
$config.Update()

Office web apps server (2013) certificate issue

If the name of the farm is different from the name of the individual office web apps server machine is there any way to deploy office web apps server with a single domain SSL certificate?
My office web apps server is working, but reporting itself unhealthy, apparently due to the fact that the SSL cert is for the name of the farm and that is different from the name of the machine.
Errors are 2004, 1004, 2156, 1156, "could not establish trust relationship for the SSL/TLS secure channel"
Going to the farm's discovery URL in the browser works fine, but going to the machine name (plus /hosting/discovery) gives an SSL error because the name of the farm is not the same as the name of the machine.
Is there any way to make it use the farm's URL instead of the machine's URL in its own internal watchdog operations? Or any way to make it use a self signed certificate on the machine's URL for it's own health checks and still use the legitimate purchased
SSL cert for user access? Or any other way you can think of to use a $5.99/yr single domain certificate instead of a $89.99/yr multiple domain certificate?
Bill Coulter

I am experiencing this same issue. The OWA server has sp1 installed. In the OWA event logs I am getting health fails for 2 events and as best I can tell it seems to be related to this issue.
We are also using a single godaddy certificate with a non machine name FQDN. Both internal and external url's of the OWA farm are set to this same name.
The problem only seems to occur with the 'Proofing Watchdog' (See events below).
Has anyone got any update on whether this is supposed to be fixed ?

Office Web Apps Server SSL Certificate

Hi
I am deploying Office Web App Server for Integration with Lync 2013. I opted for secure communication with SSL Certificate. I want this server available to internal and external users.
I am little confused over CA for Issuance of SSL Certificate. On most of the forums, I found SSL Certificate to be issued by Internal CA. If so, will this also work for external users?
If not, then plz guide me for Generating Certificate Request on Office Web App Server to be submitted to External CA for Issuance of Certificate.
Regards.

Hi,

Office Web Apps Server - Access is denied

Hello,
I was able to create an Office Web Apps server and was able to create a new farm for that server all without any issues, everything works great.
Unfortunately right after creating the farm, when attempting to run any other related powershell commands such as:
Get-OfficeWebAppsFarm
Remove-OfficeWebAppsFarm
I get this error in powershell:
Get-OfficeWebAppsFarm : Access is denied.
At line:1 char:1
+ Get-OfficeWebAppsFarm
+ ~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-OfficeWebAppsFarm], SecurityAccessDeniedException
    + FullyQualifiedErrorId : System.ServiceModel.Security.SecurityAccessDeniedException,Microsoft.Office.Web.Apps.Adm
   inistration.GetFarmCommand
Although everything is actually working on the server, I'd like to be able to use those other commands in the future so I can check configurations, use "Remove" for running updates, etc... Unfortunately it appears as though this Access is
denied error may interfere with those activities.
Has anyone seen this before?
Thank you

Hi,
According to your post, my understanding is that you failed to run any other related powershell commands after creating the farm for Office Web Apps server.
If the account trying to get OfficeWebAppsFarm does not have local admin access on the machine you will simply get an “Access is denied”.
Please make sure you have the permission to run the commands.

Office Web Apps Server IIS site disappeared?

I deployed an Office Web Apps server on a dedicated VM to be used for Lync 2013. After the initial installation / set up, I confirmed the discovery URL. It worked fine.
However, after one point in time, PowerPoint Presentations stopped working. When trying to share a PPT presentation, the Lync client popped up a message saying "Sorry, we couldn't upload <ppt file name> because we're having trouble connecting
to the service. If this keeps happening, try contacting your support team". I've done many many Lync and Office Web Apps install myself previously, and never had a message pop up like the one I saw in this case.
I tried going to the Web Apps discovery URL again, and it didn't get anywhere. I got on the Web Apps server and all the IIS sites were wiped.
I tried uninstalling the Office Web Apps server and reinstalling, but from that point on, IIS sites for Web Apps just would not appear under IIS manager.
Has anyone had similar issue with Office Web Apps?
Thanks,

Office Web Apps server / Lync server 2013

Hi I have installed a Lync 2013 Server and Office Web Apps Server. Configured Lync topology, Office Web Apps farm and certificates.
However when i start the services i get this error message in the log saying Office Web Apps discovery failed.
Event ID: 41033
Description:
Office Web Apps Server (WAC) discovery failed, PowerPoint content is disabled.
Attempted Office Web Apps Server discovery Url:
Received error message: Invalid Uri syntax for WAC configuration
The number of retries: 1,
Cause: Office Web Apps Server may be unavailable or network connectivity may have been compromised.
Resolution:
Check HTTPS connectivity from this box to the Office Web Apps Server deployment using the discovery Url.
I can access the OWAS server Url from Lync Server
Connecting to the HTTPS discovery URL is working fine, and brings up the XML-page (after i click "show all content").
The two servers are located on the same internal network, DNS resolves fine both ways, and no firewall rules blocks any connections between the two. Can anyone please help me figure this out?
Only identical problem found online is here (Invalid Uri syntax for WAC configuration):
http://blogs.technet.com/b/dodeitte/archive/2012/09/10/office-web-apps-server-amp-lync-server-2013.aspx
He resolved the problem by assigning a new OAuthTokenIssuer certificate. This however did not fix the problem in my case.

Sverre A. Veel

Hi,
In addition, please make sure you have restarted front end and office web apps server after reissuing the certificate.

SharePoint 2013 Anonymous (public) site and Office Web Apps Server 2013 issue with download.aspx

Our organization has a public facing anonymous site in SharePoint 2013 which allows access to documents (docx) in a library. ViewFormsLockdown is activated as we present the documents via CQWP / custom template. We are combating the usual
issue of multiple login prompts when using Internet Explorer when a user accesses said document. We also have tried using the Word Viewer (view only mode) from Office Web Apps Server 2013 which works well, but ...
the problem stems from the fact that users can go the file menu from the word view and choose to download the document (which is what we want), unfortunately it looks like the link redirects via /_layouts/15/download.aspx which also presents a login
prompt. Much has been written out there about doing direct links for documents via /_layouts/download.aspx to address multiple login prompts when the document is opening in word (from IE).
I've tried nearly every combination of recommendations (disabling client integration, browser file handling (permissive/strict), ViewFormsLockdown feature, web.config modifications with options and propfind verbs and more) all to varying levels of success,
but never totally getting rid of the prompt. It has been stated that because the downloads.aspx inherits from Microsoft.SharePoint.ApplicationPages.Download this will not allow anonymous access. We really want to use the word view from the Office
web app and have the file download functionality work from the menu there ... can anyone suggest an alternate fix? I might be wishing but will appreciate any guidance offered ...
cheers,
Dean
