Hi All,
I have configured Office Web App Server 2013 with SharePoint 2013. It was working fine. Yesterday my system gets shut down all of sudden due to some reason. When I tried to open office documents in our SharePoint Site in browser it gives below error. I have checked "http://servername/hosting/discovery" also, its working fine. I am unable to fine the problem where it occurred all of sudden. I am also not logged in Site with System Account.
Please help.
