FlightAware ADS-B Flight Tracking
1

Every so often I will go to my page to look at stats or flights and some times it will not show any info, like the web server is not working! I can SSH into it with no issues! I looked at the debug commands on GitHub (wiedehopf/adsb-wiki) and the only log I could see producing an error was dump978-fa. I run both 978 & 1090.

Here is part of the log,

Thing is, looking at this time is wrong! It is ahead but yet my server and 1090 logs are correct! Also on my flightaware page it is correct time! When I look at my stats page, it is also showing the date as tomorrow for aircraft reported.

Also checked for voltage issues, none exist.

Log timestamps are in UTC.

please be more specific; provide a screenshot if you can.

It can be that your 978 stick is either faulty or not connected properly.

I had the situation with my 1090 stick some months ago and identified that the USB connect was not perfect. After squeezing a bit the connector and attached it again, it was working.

You could also try a different USB port.
Are you using an extension USB cable? Can also be the root cause.
