CSRF unexpected error Help Please

In my local pc i run play 2.6 and i can´t get a single error. But in deployment as a service i get this error:
[Error] from application in application-akka.actor.default-dispatcher-11 - Error while handling error
java.lang.RuntimeException: No CSRF token was generated for this request! Is the CSRF filter installed?
or
internal server error, for (POST) [/methodName?csrfToken=token value] ->play.api.UnexpectedException: Unexpected exception[RuntimeException: No CSRF token was generated for this request! Is the CSRF filter installed?]

route code:
POST /methodName controllers.MyController.methodName()

Controller code:
public Result methodName() {
Form myClassForm = formFactory.form(MyClassForm.class).bindFromRequest();

    if (myClassForm.hasErrors()) {
        return badRequest(myClassForm.errorsAsJson());

    } else {
        session().clear();
        session("email", myClassForm.get().email);

        ObjectNode result = Json.newObject();
        result.put("Success", "Sucesso");

        return ok(result);
    }
}

View code:
@import models.forms.MyClass
@import views.html.templates.fieldTemplate
@(MyClassForm: Form[MyClass])
@import helper._
@implicitField = @{ FieldConstructor(fieldTemplate.render)}

@form(action = helper.CSRF(routes.MyController.methodName()), 'id -> “formMyClass”) {

... ... @inputText(MyClassForm("email"), '_label -> "", 'class -> "text-center textbox", 'id -> "emailId", 'placeholder -> "placeholder *", '_showConstraints -> false) @inputPassword(MyClassForm("password"), '_label -> "", 'class -> "text-center textbox", 'id -> "passwordId", 'placeholder -> "placeholder *", '_showConstraints -> false) ... }
