405 error with Ajax POST / Nginx configuration

问题

I'm trying to send email with an Ajax form and swiftmailer. It works in local but not in production.

When contact_me.php takes parameters not from form but written explicitly the email is sent even from the server so I think Swiftmailer is working.

contact_me.js

// Contact Form Scripts

$(function() {

    $("#contactForm input,#contactForm textarea").jqBootstrapValidation({
        preventSubmit: true,
        submitError: function($form, event, errors) {
            // additional error messages or events
        },
        submitSuccess: function($form, event) {
            event.preventDefault(); // prevent default submit behaviour
            // get values from FORM
            var name = $("input#name").val();
            var email = $("input#email").val();
            var phone = $("input#phone").val();
            var message = $("textarea#message").val();
            var firstName = name; // For Success/Failure Message
            // Check for white space in name for Success/Fail message
            if (firstName.indexOf(' ') >= 0) {
                firstName = name.split(' ').slice(0, -1).join(' ');
            }
            $.ajax({
                url: "././mail/contact_me.php",
                type: "POST",
                data: {
                    name: name,
                    phone: phone,
                    email: email,
                    message: message
                },
                dataType: "text",
                cache: false,
                success: function() {
                    // Success message       
                },
                error: function() {
                    // Fail message                    
                },
            });
        },
        filter: function() {
            return $(this).is(":visible");
        },
    });

    $("a[data-toggle=\"tab\"]").click(function(e) {
        e.preventDefault();
        $(this).tab("show");
    });
});


/*When clicking on Full hide fail/success boxes */
$('#name').focus(function() {
    $('#success').html('');
});
