I followed these instructions to successfully install and start PiAware on an RPi B 3+ that was already configured as an OctoPi to monitor 3D printing. The only issue I have is trying to direct connect to monitor my data via SkyAware. When I click “View live data” my browser says it cannot reach the site (192.168.1.6:8080). I assume this has something to do with the OctoPi also running on that RPi since typing in 192.168.1.6 brings me to the OctoPi web interface. Do I need to simply change the port in the PiAware configuration to something other than 8080 so that I can connect to SkyAware?
This is a shot in the dark mate as I’m not super familiar with OctoPi, but I think it already has a webserver defaulting webcam or something like that on :8080. Perhaps try 192.168.1.6/dump1090-fa/
Like I said, shot in the dark, but without asking a zillion questions about your current webserver config, it’s worth a quick try.
I think you’re right. I tried your suggestion, but it didn’t work.
A bit more invasive, but give this a whirl if you are bored:
sudo nano /etc/lighttpd/conf-enabled/89-dump1090-fa.conf
change the 8080 to a different port, maybe 8090 for a test then save
sudo systemctl restart lighttpd
Then try to reach it on 192.168.1.6:8090

Sorry bud. I am not privy to whatever webserver setup that currently resides within the OctoPi image to be much more help. Someone smart here I’m sure has already been through this, so hopefully they can chime in.
The page is called debug commands, thus yes and share the results (last 30 lines for each command are sufficient).
Sometimes i think … things are obvious but obviously they are not.

Let’s try again, but restart lighttpd first.
sudo systemctl restart lighttpd
sudo journalctl --no-pager -u lighttpd
This doesn’t work? What does it say?
http://192.168.1.6/dump1090-fa
Honestly OctoPi have taken over lighttpd … which is annoying to debug.
You could install nginx, configure it to a different port, install tar1090 and include the file provided by tar1090.
But that reqires some basic understanding of how to configure nginx.
(GitHub - wiedehopf/tar1090: Provides an improved webinterface for use with ADS-B decoders readsb / dump1090-fa)
I think it may be due to HAProxy that’s probably already on his system as an intermediary. Per the above, I had him reroute the listener to :8090 and that didn’t work…
sudo cat /etc/haproxy/haproxy.cfg
No clue what the extra layer does to the listeners if it’s installed - I’ve never found a use for these extra layers as I find it simpler to set everything up properly in the webserver configs themselves, so no experience with these “bandaids” – If this is the issue in the first place. Grabbing at straws and that’s all we can do unless we’re sitting there.
Installing yet another webserver would complicate matters even more imho.
Might well be 
Didn’t know haproxy was installed.

Figured as much. Going to need to get some help from someone who has messed with haproxy. No clue why a dist would have a need for that on an SBC of all things, but is what it is. Between that and lighttpd crapping out, not sure where to begin since this is not a typical setup.
@Nitr0 I have a YouTube & Google level education in Linux, so unfortunately I’m not sure what to make of that. This was my first attempt to use an RPi for a secondary purpose. It would have been nice if just changing the port did what I needed, but I’m good to either live without SkyAware or just buy another RPi for dedicated use. Thanks again for trying to help this noob!
I’m sure there is an easy workaround. Do you still have port 8090 set from when you tried above?
sudo systemctl status lighttpd
That might give a little more information where the service goes south. You’ll never get a webpage without the webserver running. It could be as simple as adding another entry in the haproxy.cfg file to allow port 8090. 8080 is already being used for your webcam in OctoPi - although I guarantee that’s not working either right now… I have zero experience with haproxy and can’t for the life of me fathom why it would be needed in the first place as there are webserver config files for a reason. They must have had some good reason I guess.
Correct, my webcam is not loading. I haven’t been using my 3D printer, so I haven’t bothered troubleshooting it. Maybe we could solve two things for the price of one!
