I have a SharePoint set up with two site collections:
I also have an Office Web App server that is currently working with the first site collection. I can click on PPT/Word/etc. documents in the first site and it will open it up in Office Web Apps.
When I try to open up documents in Office Web Apps on site2, I get the following error:
“WOPICheckFile,WACSERVER HttpRequestAsyncException [url:https://site2.company.com/spin/_vti_bin/wopi.ashx/files/XXXXXX?access_token=REDACTED_XXXX&access_token_ttl=XXXX, e:Microsoft.Office.Web.Apps.Common.HttpRequestAsyncException: No Response in WebException ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure. at System.Net.TlsStream.EndWrite(IAsyncResult asyncResult) at System.Net.ConnectStream.WriteHeadersCallback(IAsyncResult ar) - -- End of inner exception stack trace --- at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at Microsoft.Office.Web.Apps.Common.HttpRequestAsync.GetResponseCallback(IAsyncResult asyncResult) - -- End of inner exception stack trace ---, host correlation:]”
The weird thing is that I am able to open Excel spreadsheets without a problem. Word/PPT/PDF/etc. are not working though. Opening up any document in the desktop office app also works fine.
I made sure that I have a working certificate for site #2 (cert is for domain *.site2.company.com).
Has anyone seen this issue before?
