Solve.
Change in void Application_Error() in Global.asax.cs
Check type of last server error to HttpRequestValidationException and redirect to CustoErrorPage.html

C#

void Application_Error(object sender, EventArgs e)
        {
            if (typeof(System.Web.HttpRequestValidationException) ==  Server.GetLastError().GetType())
            {
                
                Response.Redirect("~/HTML/CustomErrorPage.htm");
            }

        }
