Today I found Office Web apps are working only in Chrome. Initially I was getting the following error (to start previews, please log on by opening the document)
in my OWA ULS logs when I try to preview a document:
Health report by WebOneNoteWatchdog: Agent: WebOneNote, eventId: 1206, eventType: Error, categoryId: 0, eventMessage: <?xml version=”1.0″ encoding=”utf-16″?> <HealthReport xmlns:xsd=”http://www.w3.org/2001/XMLSchema” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”> <HealthMessage>WebOneNoteWatchdog reported status for WebOneNote in category ‘Ping’. Reported status: Contact the OneNote.ashx web service failed with an exception: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. —>
Health report by WebOneNoteWatchdog (persistent): Agent: WebOneNote, eventId: 2206, eventType: Error, categoryId: 0
Even after I opened the document this warning doesn’t go away.
The certificates are valid. IE is not complaining and also Chrome is not complaining when I open the page/documents. So it looks like this is an issue with Chrome only.
