Regions Ping Always 0

I'm connecting to the NameServer to get a list of all severs and list it to the player with each current ping, but the ping value that i get is always 0.

public override void Show(bool p_show)
    {
        foreach (Region __region in PhotonNetwork.networkingPeer.AvailableRegions)
        {
            RegionBar __regionBar = Instantiate(regionBarPrefab);

            __regionBar.regionLabel.text = __region.Code.ToString();
            __regionBar.pingLabel.text = "Ping: " + __region.Ping; //Always 0
            __regionBar.region = __region;
            
            __regionBar.transform.SetParent(regionBarGrid.transform);

            _regionBars.Add(__regionBar);
        }

        base.Show(p_show);

        _displaying = true;
    }

void Update()
    {
        if (!_displaying)
            return;
        
        foreach (RegionBar __regionBar in _regionBars)
        {
            __regionBar.pingLabel.text = "Ping: " + __regionBar.region.Ping;  //Always 0
        }
    }

What am i doing wrong, do i have to manually send a ping command ? If so, how do i do this ?
