Wow that’s a lot of errors! But luckily for us, they all stem from one cause.
On the WAC server, all IIS websites and application pools were started. On the WAC server, any Office Web Apps powershell you would run would give the error “ It does not appear that this machine is part of an Office Web Apps Server farm.” This includes Get-OfficeWebAppsFarm, Set-OfficeWebAppsFarm, etc. The certificate specified in farm settings was not found in the store. Could not provision HTTPS endpoint because the certificate was not specified, not found, or invalid. There was a pre-existing event for the UlsController service. This is often caused by an incorrect address or SOAP action. Error when trying to connect to Farm State Manager service: : There was no endpoint listening at that could accept the message. On the WAC server in the Microsoft Office Web Apps event log would be these errors:. System.InvalidOperationException: The certificate has not been specified.” After a server reboot and using Process Explorer to kill some processes, it would give this error when trying to start: “ Service cannot be started. System.IO.IOException: The process cannot access the file 'C:\ProgramData\Microsoft\OfficeWebApps\Data\local\ULSConfig\' because it is being used by another process.” It would log this Event ID 0 error in the Event logs: “ Service cannot be started. On the WAC server, the Office Web Apps server would not start. 
The output of Get-WOPIZone on the SharePoint server looked fine.Attempting to open the URL for Office web apps like gave the same error “This page could not be displayed”.It gave the the error “ This page could not be displayed”. SharePoint would not render any previews of Office documents, nor could you open any files in Office in the browser.We saw a lot of symptoms for this problem and they included: The Errorsįor the record, this server was Office Web Apps 2013 and this was the only server hosting the WAC farm. This turned out to be a simple fix but took some hair-pulling to get there, so let me share my journey.
If you are like my unfortunate client, your installation of Office Web Apps (or WAC) was humming along just fine until that one day comes that you wish you never got out of bed.
