Sorry, We couldn't find your file. is it possible it was moved, renamed or deleted? SharePoint 2013,SkyDrive,OneDrive,Office Web Apps

I was trying to Edit a document -which hosted on SharePoint- in client side Word application , but I faced this error "Sorry, We couldn't find your file. is it possible it was moved, renamed or deleted? " followed by half of the URL.

After alot of trails I found the best ways to solve this issue, as it was not clear in most of the websites.

First:
Restart-Service AppFabricCachingService

Second:
You have to check the client side, as my problem was there, my Microsoft Office edition didn't allow me to open the file, Try to Repair it , or better to UnInstall then Install it again


Last:
Use the following PowerShell in your environment:

$config = (Get-SPSecurityTokenServiceConfig)
$config.AllowOAuthOverHttp = $true
$config.Update()
