    Check dump1090-mutability settings:
    Code:
    sudo nano /etc/default/dump1090-mutability
    Comment NET_BIND_ADDRESS= line (if not commented).
    Code:
    # Bind ports on a particular address. If unset, binds to
    #all interfaces.
    # This defaults to binding to localhost. If you need to allow remote
    # connections, change this.
    #NET_BIND_ADDRESS=

    You are back on sync matrix but not synced with any other station again.
    First idea:
    - take new SD card, burn Raspbian and install dump1090-mutability, adsbx mlat-client
    2nd one:
    - check your router settings (firewall can block incoming connections, port forwarding is not necessary).
    3rd one (can cause that your IP will be blocked):
    - change port in adsbexchange-mlat_maint.sh from 30005 to 30002.
    4th one
    - add adsb-receiver to your image (it will ask if you want to update dump1090-mutability, select yes and don't install any other feeder but portal only - it will allow you to have basic stats of your feeder).
    Your case is really difficult.

    That is odd. I wonder why he won't sync. sync is based on utc time with others around him .... that's odd.

    Sorry took so long to get back. Took ages to get connected to your MLAT server again.

    So as you see it's still not synching. Router is not blocking any outgoing connections and I have even tried running mlat-client on my windows laptop with feed coming from the pi. I could wireshark and confirm connection to your server, but same results, no sync.

    When you suggest changing port, do you mean use the raw o/p feed from dump1090 to mlat? Sure can try it.

    Will try the raspian image later or on weekend.

    I hadn't tried port 30002 so won't bother.
    I'm going to get pi down from attic and install rasbian from scratch and try the adsb-receiver. May just give installing dump1090 and mlat separately 1st though. Thanks for the link with instructions.
    Will let you know how it goes over weekend.

    Be careful with adsb receiver, don't install mlat client, only dump1090-mutability and portal (other feeders are OK if you want to install them). Install mlat client as described in section "How to feed".
    After installing dump with adsb-receiver you'll probably need to edit config.js to properly display range rings.
    I'm waiting for your mlat :)

    I wish I had a solution for this but .... everything seems to be as it should from that config.

    I'm rebuilding pi now. However, forgot to make note of the custom port I should be using to feed adsbexchange. Any chance someone can check and send it to me please

    Thanks, managed to mount old image and found port I was using that's registered to me.

    All rebuilt, waiting to reconnect to mlat server. maybe a long wait :(

    Everything works, your feeder can sync. Thanks to James or reconfiguration.
    Anyway enjoy your feeding.

    Thanks MDA and James.

    Yes, that's my data on the custom feed and yes after the rebuild and manual install (Didn't use the image this time just the plain Rasbian image) all sync is working. :)
