How can I change OSRM server with leaflet-routing-machine

I am using leaflet-routing-machine with OSRM, How can I change OSRM server and do not use demo?

I have the same warning:

You are using OSRM's demo server. Please note that it is **NOT SUITABLE FOR PRODUCTION       USE**.
Refer to the demo server's usage policy: https://github.com/Project-OSRM/osrm-backend   /wiki/Api-usage-policy

To change, set the serviceUrl option.

Please do not report issues with this server to neither Leaflet Routing Machine or OSRM -   it's for
demo only, and will sometimes not be available, or work in unexpected ways.

Please set up your own OSRM server, or use a paid service provider for production.

Today, the routes have not showed and I have the same error in Firefox:

Routing error: 
Object { message: "HTTP request failed: abort", url: "https://router.project-osrm.org/route   /v1/driving/-4.772748,3…38.013284?overview=false&alternatives=true&steps=true&hints=;", status:    -1, target: abort }

In Chrome:

It is my code:

    L.tileLayer('https://{s}.tile.osm.org/{z}/{x}/{y}.png', {
      attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
    }).addTo(map);

  let control = L.Routing.control({
  waypoints: [
    L.latLng(origin_latitude, origin_longitude),
    L.latLng(destination_latitude, destination_longitude)
  ],
  plan: L.Routing.plan([
    L.latLng(origin_latitude, origin_longitude),
    L.latLng(destination_latitude, destination_longitude)
  ], {
    createMarker: function(i, wp) {
      return L.marker(wp.latLng, {
        draggable: false
      });
    }
  }),
  addWaypoints: false,
  routeWhileDragging: false,
  draggableWaypoints : false,
  show: false,
}).addTo(map);
