Dump1090-fa web panel showing 404-not found

FlightAware ADS-B Flight Tracking
1

Hi everyone

I have had my pi 4 running for ages but the other week I’ve had a powercut (Might be during an update not 100%)

The Dump1090-FA site comes back as 404 not found error. I’ve uninstalled and reinstalled dump1090-fa but the web site doesn’t display however it is feeding data.

Any ideas?

Try
Clear browser cache (Ctrl+Shift+Delete).
Reload browser (Ctrl+F5).

Also check router for any change in local IP of Pi4.

You can also find current local IP from your Flightaware stats page.

Its the same on my phone and its the same IP.

check if it’s running.

sudo systemctl status dump1090-fa

and of course the correct URL http:///dump1090-fa or http://:8080/dump1090-fa

Error 404 means “page not found” so the webserver is running, but can’t deliver the webpages of dump1090

I just checked

Strangely tar1090 works

@stephenkurtianyk
What is the output of this command?

sudo systemctl status lighttpd

7

Would tar1090 work if this is not running?

Try purging, then reinstalling dump1090-fa
If that does not solved the issue, then easiest solution is to reimage the microSD card.

sudo apt-get purge dump1090-fa  

sudo apt-get install dump1090-fa

sudo reboot

That fixed it thank you so much!

Whats the different between remove and purge?

11

remove deletes the packages.
purge deletes the packages AND deletes the configuration files too.
