FlightRadar24 - Radar Status = Offline yet everything is running ok.

[Litmus]

So this morning I got an email that my Radar in FlightRadar24 app shows "Offline" so I checked the laptop running the software and everything checked out ok. I even rebooted and started everything anew. Piaware is running, MLAT, Beast, and everything is running perfectly. Dump1090 is fine. But the app still shows the Radar to be offline. What gives?

I took screenshots of everything.

Same thing for me. And besides that, my stats was gone and my account downgraded to basic.

My feeder has been up and working (responding to the local web-interface) with aircrafts listed as tracked all the time.

[Litmus]

Good morning,

I figured out the problem. The software that runs the Feeder was outdated and I updated it. Everything is running OK now.

So, here's what I did.

First, stop the feeder and terminate the software (your feeder IP address:8754)
On your Linux box: sudo bash -c "$(wget -O - https://repo-feed.flightradar24.com/install_fr24_linux.sh)"
It will ask you for your email, sharing key, etc.
Restart the feeder and REBOOT the Linux box.
Restart piaware

Let me know if this works for you, good luck!!

About a week ago my FR24 feed stopped - FA is still feeding (including MLAT), and the Pi hadn't rebooted.

I checked the version of FR, and got back this:


pi@PiPlane3B:~ $ sudo apt-get update

Version table:
*** 1.0.29-10 100
100 /var/lib/dpkg/status

Which I interpret as saying I have the latest version of FR.
When I check the status of my fr24feed, I see this:

pi@PiPlane3B:~ $ sudo fr24feed-status
FR24 Feeder/Decoder Process: running.
FR24 Stats Timestamp: 2023-12-13 16:53:03.
FR24 Link: unknown ... failed!
Receiver: connected (11589834 MSGS/0 SYNC).
FR24 MLAT: not running ... failed!

I searched the forum for the string "FR24 Link: unknown ... failed!"


and quickly found myself in over my (non-Linux savvy) head.
I expect the solution here is "obvious" to a more experienced Linux and FR24/FA user - maybe someone can point me in the right direction?

Thanks.

You are a victim of this

https://forum.flightradar24.com/forum/radar-forums/flightradar24-feeding-data-to-flightradar24/222778-feed-versions-below-1-0-30-unsupported

are you on a standard Pi software base?
Abcd has some details on updating the .deb directly using wget
But for some reason your repo is not updating

https://repo-feed.flightradar24.com/rpi_binaries/fr24feed_1.0.44-0_armhf.deb

[SD_Mark]

Oblivian thanks for the help. The confusing (to me) aspect here is that when I do a version check, I'm told I'm on the current version

pi@PiPlane3B:~ $ sudo apt-cache policy fr24feed
fr24feed:
Installed: 1.0.29-10
Candidate: 1.0.29-10
Version table:
*** 1.0.29-10 100
100 /var/lib/dpkg/status

When I run
sudo apt-get update
sudo apt-get install fr24feed

I get back
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
fr24feed is already the newest version (1.0.29-10).
The following package was automatically installed and is no longer required:
libminizip1
Use 'sudo apt autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 236 not upgraded.

which is obviously less than the version you reference here (1.0.44) - why is my Pi confused on this?

So I guess I need to manually force it from the repository (?)
Wget https://repo-feed.flightradar24.com/...44-0_armhf.deb
sudo dpkg -i fr24feed_1.0.44-0_armhf.deb

I'm running a pretty vanilla install (just feeding FA and FR24) - on Bullseye, which was current when I set this up (it's just been chugging away since July '22).

As noted, I'm pretty much a Linux noob, so I haven't monkeyed with anything there. It appears Bookworm came out a couple months ago - and I haven't installed it. Should I consider doing that, or perhaps just update Bullseye (I'm sure there are fixes to that) without going all the way to Bookworm?

If so, is there a preferred order to this - update Raspbian first, and then FR24?

[Oblivian]

You need to totally reinstall for bookworm. Don't go that far unless you get a new pi 5 at this time.

No answer sorry. Possibly something to do with your build/install process at the start..True 64 and Linux always behind Pi build.
May need manual repo file update.

Wget the url I posted
Then
Sudo dpkg -i fr24feed_1.0.44-0_armhf.deb

[Oblivian]

It's copy pasted the '...'s

You need to get the full url from rt Click/long click not copy the text

I've made a quick code edit to fix that

[SD_Mark]

The file was found and I installed it. After a reboot:
pi@PiPlane3B:~ $ frstat
FR24 Feeder/Decoder Process: running.
FR24 Stats Timestamp: 2023-12-13 19:35:08.
FR24 Link: connected [UDP].
FR24 Radar: T-KCRQ46.
FR24 Tracked AC: 148.
Receiver: connected (51133 MSGS/0 SYNC).
FR24 MLAT: not running ... failed!

So looks like it's mostly working, but MLAT isn't happy. Maybe that will resolve itself in time?

Thanks for getting me back online.

[SD_Mark]

Never mind. I found this:

https://forum.flightradar24.com/forum/radar-forums/flightradar24-feeding-data-to-flightradar24/213550-disable-mlat-if-sharing-with-other-networks

So I probably already turned it off (am feeding FA) and forgot I did so.

[Litmus]

After reading the issues you had with your Pi, I will leave my one install alone and repurpose the Pi for something else. Yikes!
