w3wp.exe (0x1CA0) 0x44B0 SharePoint Foundation General aat87 Monitorable An error has occurred on the server.

when we browsed to this URL on OWA farm:
OfficeWebAppsServerFQDN/op/generate.aspx

We were getting this error:

Server Error
We’re sorry. An error has occurred.
We’ve logged the error for the server administrator.

We checked that ‘OpenFromUrlEnabled’ property on OWA farm was set to false.
Ran this command to set property to true.
Set-OfficeWebAppsFarm -OpenFromUrlEnabled:$true
Now If we browse to this URL: OfficeWebAppsServerFQDN/op/generate.aspx, It results page correctly.

But documents were still giving error when opening in browser.
So, we are able to view Office documents using the Office Web Apps 2013 viewer Hence didn’t seem to be an Office web apps issue.
After further investigation we found that : 3rd party software: “Dell change auditor agent” was causing it to fail.
After we stopped “Dell change auditor agent” service on SharePoint server and restarted IIS, Office Web Apps started to work.
Dell is already aware of this issue.

Likewise, other 3rd Party softwares can cause this issue.
