During a SharePoint 2013 deployment, integrated Office Web Apps 2013 with SharePoint 2013 with my implementation guide How to Install and Configure Office Web Apps 2013 for SharePoint 2013. Everything went well until we received all of the Office Web Apps services failing errors in SharePoint 2013.
Word Web Apps gave an error:
“Sorry, there was a problem and we can’t open this document. If this happens again, try opening the document in Microsoft Word.”
So, Make sure Office Web Apps server is able to contact SharePoint sites to get rid of these issues.
