Resolution summary: Would suggest to read the complete article but just for quick reference I am typing the resolution here.

%windir%\system32\inetsrv\appcmd set config "Default Web Site" -section:system.webServer/security/requestfiltering - allowDoubleEscaping="true"

Or change manually by opening the following file

and change following value.
