    Is it Raspbian 64bit?

    I'd generally recommend a standalone decoder and then adding fr24:
    Raspbian Lite: ADS B receiver
    https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver
    Solutions to common problems using dump1090 variants and ADS-B feeders - wiedehopf/adsb-wiki


    That way if fr24feed doesn't work properly, you still have local reception and the components are independent.

    Oh i know the issue, you don't just start fr24feed via the command line, you use it via the fr24feed.service
    Google how to restart and check logs for systemd services.

      Welcome onboard Captain!

      Raspian is 32 bit.

      And started the service:

      zoli@rpi:~ $ sudo systemctl is-enabled fr24feed.service
      enabled

      FR24 LOG:


      2022-05-08 15:47:21 | [main][i]Terminating child process 3686 with SIGTERM
      2022-05-08 15:47:21 | [reader][i]Connection terminated

      Is seems after connecting...connection terminated, but why?

        sudo journalctl -u fr24feed -e -f

        Really that's not sufficient log, if it's not saying anything else i'd just recommend install a standalone decoder as described in the link in my previous post.
        Then you also have graphs1090 if the signal is an issue.

        Do you still have the other thing running on the console? Stop it. It must only run via the service.

          dev/shm/decoder.txt: Permission denied error | write_locked - missing monitor file pointer
          looks as starting the service that way isn't happy. It should have permission to write what's being captured and thus send it I'd have thought


          (And connection terminated is 'its already running and I cant restart it' normally.

          Just break away from fr24 dump1090 as suggested.

            PROBLEM SOLVED:

            Thanks a lot mates. This one helped:

            Automatic installation for readsb
            https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb
            Solutions to common problems for rtl_sdr / ADS-B stuff - wiedehopf/adsb-scripts


            This method solved everything, uninstalled previous decoder and reconfigured fr24feed.

            My radar is : T-LHNY8, you can check live data at FR24.
