Seeing 502 Bad Gateway errors on adsbexchange-stats.service logs

Hello, I just setup my Raspberry Pi today for ADSB Exchange. Everything seems to be working fine, but I am noticing 502 Bad Gateway errors in the adsbexchange-stats.service logs. I’m not sure what this service does so wanted to check here to see if this is something I should be worried about. Here is an example of the errors:

cloudflare

Also, after a reboot I’m seeing this:
Sep 21 20:58:08 adsbexchange systemd[1]: Started ADSBexchange Stats.

Thanks in advance for any insight into this.

That would be a backend Issue so nothing to worry about on your end.

Thanks CommGuy. I forgot to ask, I get this line every time I reboot. Do I need to worry about it?

No valid data source directory found, do you have the adsbexchange feed scripts installed? Tried each of: [/run/readsb /run/adsbexchange-feed]

Does your feeder see aircraft on the local map and does https://www.adsbexchange.com/myip/ show all Green? If so you should be good.

It sure does. I have green “Feed Ok” on the left box and “Stats Ok” on the right box. I’m also seeing aircraft on my local map. So sounds like I can ignore this message as well.
When I first installed things, the right box said that I needed to run the commands to install the stats program, but then it auto cleared and went green so I got concerned that I missed a step.

Thanks for confirming that all is working as expected CommGuy.

You really need to wait a few minutes or so for everything to sync up before checking the MyIP page or you can see false errors. If you used the feeder image it here is no need to even hook a monitor to the pi it can all be done via web browser.
