I have recently configure existing Office Webs to use SSL and https url. Our configuration is 1 SharePoint server and 1 SharePoint Web Apps.

In Office WebApps Server

 Set-OfficeWebAppsFarm -InternalURL "https://contoso.com/" -ExternalURL "https://contoso.com/" -SSLOffloaded -certificate "contoso.com2022" -AllowHTTP:$True

It configured without any issues.

In SharePoint server.

  1. Removed all exisiting binding

    Remove-SPWOPIBinding -All

  2. Binding again

    New-SPWOPIBinding -ServerName "CONTOSO.COM" -AllowHTTP

  3. Set WOPI ZOne

    Set-SPWOPIZone -zone "internal-http"

In the SharePoint site. When I tried to search any document with pdf, excel or word. It did not display preview and not error display as well. When I attempt to open any document, it downloaded the document instead preview in browser. Before configure using SSL and https, it working fine.

Anything that I missed?

  • If you log on to SharePoint 2013 by using the System Account, you won't be able to test the connection between SharePoint 2013 and Office Web Apps Server. Log on with a different account to test the connection. Commented May 11, 2022 at 4:36
  • No , I am checking in the browser outside the server using normal account
