ERROR MESSAGE WITH DUMP90 GMAP PAGE FR24

[medlege]

Hello to all of you !
Hope that your are all fine !

Please since 2 or 3 days I notice an error message when going on the FR24 dump90 gmap page of the FR24 Pi. It is writen in a yellow square : ""Problem fetching data from dump1090.
AJAX call failed (error: Not Found). Maybe dump1090 is no longer running?
The display map data will be out of date"

The aircraft "tracked" and "uploaded" and "show tracked list" always remains "zero" in number even in presence of planes !! Thus making the radar "Online - no data" all the times with zero stats...

But I can clearly see all the planes in the others sites I feed without any trouble (Radarbox24, planefinder, Flightaware) with the same Pi...!!

So why not working in FR24 and working good with all the others ?
I think there is a trouble with the dump90...
It happens suddenly !!
Did you face this issu please ?

Need your precious help !!
Have a nice day and best regards.

Hi medlege
I did NOT request you to post screenshot of error message, as your description of error message in your first post was clear enough. I gave you 3 commands and asked you to issue these commands and post their output.

What I need is to find out what software you have installed. This will be made known by the output of three commands I posted in my previous post. Please issue these commands and post their output.

I am suspecting that you have intentionally (or unknowingly) installed dump1090-fa, while there was dump1090-mutability already installed by FR24 feeder. Simultaneously running two versions of dump1090 causes such issues. If this is the case, then:

• The dongle is grabbed by dump1090-fa which is working OK.
  
• The dump1090-mutability does not get the dongle so it fails. This gives the map error you have described.
  
• As FR24 feeder is configured to receive data from its dump1090-mutability, and dump1090-mutability has failed, in FR24 the aircraft tracked and aircraft uploaded are both ZERO.
  
• All other feeders get data from dump1090-fa and are working OK.

Please issue the 3 commands I have given in my last post, and post their output. Without knowing this info, I cannot be sure if what I suspect and described above is the actual cause of your problem. I repeat these commands below:

Code: [Select]

apt policy dump1090-mutability

apt policy dump1090-fa

lsb_release -sc

I am facing big difficulties to reply to your post...
Always an error message telling me to wait few minutes for spam raison...

I have typed the 3 command Please see the attached file for the 3 output.

And you resume perfectly my case. My exact situation.
I have a FR24 Pi24 image and I have installed on it the others feeders, Radarbox24, flightaware and planefinder.
I never make any change so surely dump-fa installed automatically with Piaware feeder update 3.8.1... Creating this issue with Flightradar24.

Thanks again for your so precious help.
Waiting for your answer Please.
Best.

Very strange your installation is refusing all standard commands.

Please post output of these three commands:

Code: [Select]

sudo systemctl status dump1090-fa   



Code: [Select]

cat /etc/os-release



Code: [Select]

cat /etc/fr24feed.ini     



[medlege]

Maybe because I have the same old jessie Pi24 ?

Please see the attached file for the 3 output.
Thanks.
Waiting your answer.
Best.

Your case is exactly like I suspected. You have installed dump1090-fa, and your setting receiver="dvbt" causes fr24feed to run dump1090-mutability. This is causing conflict.

As in file fr24feed.ini, you already have procargs="--net", do this, and all will be ok.

Code: [Select]

sudo apt-get purge dump1090-fa
sudo reboot

Hello abcd567,
A Master !!

Thank you sooo much I made the command and everything is back to normal as usual ! dump1090 mutability working good with FR24 and the others feeders also working good !
So happy to get back online with data and stats !
Last year I made this installation thanks to your precious help and to also the help of others persons on this important forum.

As I told you I suspect that dump-fa surely installed automatically with a recent Piaware feeder only update as I never make any installation or touch anything in the Pi ! Really I just let the Pi work and have the update alone !
So that is why I am so surprised and amazed how this could happened !!
Hope that dump-fa will not install again in the future !

Once again thank you very very much abcd567 !!
Wouldn't make it without your help !!
Have a nice day.
Best wishes.
