Connect Office Web App Server to Sharepoint 2013

Hi,

I am upgrading Sharepoint 2010 to Sharepoint 2013. Everything looks fine.

I installed á new Office WEb apps server on Windows 2012 with all new updates from Microsoft.

I ran this command "NEW-OfficeWebAppsFarm –InternalUrl “http://xxxxxxxx01” -ExternalUrl https://xxxxxxxx01–CertificateName"OfficeWebApps" -EditingEnabled" I have also tried using https on both internal an d external.

I ran this on Sharepoint 2013

"##Connecting SharePoint Farm to Office Web App Server

 Add-PsSnapin Microsoft.SharePoint.PowerShell

 ##Variables

 $OffWebAppSrv="xxxxxxx01"

 #####DO Not Edit Below this line

 "Connecting to $OffWebAppSrv"

 New-SPWOPIBinding -ServerName $OffWebAppSrv -AllowHTTP

 "Setting Zone"

 Set-SPWopiZone internal-http

 "Script Completed"

No errors.

I have done IIS reset and restarted the servers serveral times.

When I try to open document  I get Error "Sorry something went Wrong"

I can not see anything in logs showing the reason for the error.

pls adv,

New-SPWOPIBinding-ServerName$OffWebAppSrv-AllowHTTP

"Setting Zone"

Set-SPWopiZoneinternal-http

"Script Completed"
