"SkyAware unknown version" error searching

My RBPi4 at home is acting up. I get the error “SkyAware unknown version” but also dump1090-fa does not seem to report any data. I have restarted, rebooted and hardware reset (pulled the plug) but the problem persists. It works for a while but then stops. Not consitent. Is it the sd-card that is failing? The Pi has no other software running on it except dump1090-fa and several feeders.

After a reboot;

● dump1090-fa.service - dump1090 ADS-B receiver (FlightAware customization)
   Loaded: loaded (/lib/systemd/system/dump1090-fa.service; enabled; vendor preset: enabled)

Rebooted and now it is currently running.

Sorry, I mean capture that when it’s having problems. The log you posted looks normal.

Of course. :slight_smile: Will do!

I also get in SkyAware messages (a yellow box popping up now and then) “problems fetching data from Dump1090. Ajax …” but just for a couple of seconds then it disappears.

Intermittent warnings like that (especially if it says “timeout”) are often caused by poor wifi connectivity.

While trying to eliminate problems I removed the 50 cm USB extension cable that I used so that the RB flightstick would not heat up the Pi. After this no problems have been seen, so I must conclude that there is a connection error using the cable.
