WebApi 2.1 PUT throw error 415

I'm trying to update data using WebApi PUT method. My code working fine before, but suddenly I start to get this error.

"Message":"The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type 'xEmployee' from content with media type 'application/octet-stream'.","ExceptionType":"System.Net.Http.UnsupportedMediaTypeException".

This is headers: Response Header.

Nothing special in Controller code:

[Authorize(Roles = "Admin, User")]
        public async Task<IHttpActionResult> PutxEmployee(int id, xEmployee xEmployee)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            if (id != xEmployee.Kod)
            {
                return BadRequest();
            }

            try
            {
                var user = db.xEmployee.Find(id);
                user.Сотрудник = xEmployee.Сотрудник;
                user.Telephon = xEmployee.Telephon;
                user.Password = xEmployee.Password;
                user.email = xEmployee.email;
                await db.SaveChangesAsync();
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!xEmployeeExists(id))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }
            catch (DbEntityValidationException e)
            {
                foreach (var eve in e.EntityValidationErrors)
                {
                    var path = "C:/error.txt";
                    using (StreamWriter sw = File.CreateText(path))
                    {
                        sw.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",
                                eve.Entry.Entity.GetType().Name, eve.Entry.State);
                    }
                    using (StreamWriter sw1 = File.CreateText("C:/error1.txt"))
                        foreach (var ve in eve.ValidationErrors)
                        {
                            sw1.WriteLine("- Property: \"{0}\", Error: \"{1}\"",
                                ve.PropertyName, ve.ErrorMessage);
                        }
                }
                throw;
            }
            return StatusCode(HttpStatusCode.NoContent);
        }

Same as WebApiConfig:

public static void Register(HttpConfiguration config)
        {
            config.MapHttpAttributeRoutes();
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
            var json = config.Formatters.JsonFormatter;
            json.SerializerSettings.Culture = new CultureInfo("ru-RU");
            config.Formatters.Remove(config.Formatters.XmlFormatter);
        }

There seems to be a typo (last ") in the request's Content-Type header:

Content-Type: application/json; charset=UTF-8"

When this header is missing or malformed, the server will automatically use application/octet-stream by default, as described by this post.
