[No Web UI?]

I've been beating my head against the wall for 2 days straight trying to get this to work.  I've performed a fresh installation of btsync.  From what I can read, after the install, the webui should be available immediately after install so that it can be configured further.  However, I can't get it to show up at all.  Here is my config:

{
    "storage_path" : "/var/lib/btsync/",
    "vendor": "tuxpoldo",
    "display_new_version": false,
    "disk_low_priority" : true,
    "lan_encrypt_data" : true,
    "rate_limit_local_peers" : false,
    "folder_rescan_interval" : 600,
    "folder_defaults.delete_to_trash" : true,
    "folder_defaults.use_dht" : false,
    "folder_defaults.use_lan_broadcast" : true,
    "folder_defaults.use_relay" : true,
    "folder_defaults.use_tracker" : true,
    "folder_defaults.known_hosts" : "",
    "webui" :
    {
        "directory_root" : "/home/rtorrent/btsync",
        "listen" : "0.0.0.0:8888",
        "force_https" : false,
        "ssl_certificate" : "/etc/btsync/debconf-default.crt",
        "ssl_private_key" : "/etc/btsync/debconf-default.key"
    }
}

 

I do have some weird errors in sync.log:

I suspect the problem is where it says it is using IP address 127.0.0.2, but I have no idea why it would do that.
