Unable to listen on IPv4 port 5000
-
I am trying to follow the setup guideline for the airplay speaker project (https://docs.onion.io/omega2-project-book-vol1/airplay-audio-receiver.html) but can't seem to work anymore.
So I successfully set it up on a different wifi network once, but then when I tried to use it somewhere else it stopped working. I knew I need to change the wifi setup, which I did too. I kinda wanted to get it down quickly so I thought I will just reformat it and then try to redo every step again, but then I couldn't make it work again.
When I started the service at the last step with
shairport-sync -d, I couldn't see it on my iPhone. So first I checked if the daemon is running withps | grep shairwhich showed it runs:1887 root 4360 S /usr/bin/shairport-sync -c /var/etc/shairport-sync-shairport_sync.conf 2029 root 1216 S grep shairThen I checked the following too:

Is another instance of Shairport Sync running on this device? Request to shut down all rtsp conversation threads asking playing threads to stopSo I could see there was some issues and couldn't start properly and has to do with port 5000. Then I wanted to check if something else maybe running on port 5000, so I did:

I am using an Omega2 with an Expansion Dock.
I also edited the config file at
/etc/config/shairport-synclike :# Use OpenWrt UCI config config shairport-sync 'shairport_sync' option enabled '1' option respawn '1' ... option name 'Shairport-Sync-%v-%h' option password '' ... option mdns_backend 'tinysvcmdns' # avahi/external-avahi/dns-sd/external-dns-sd/tinysvcmdnsDoes anyone have some ideas or suggestions how can I resolve the issue with port 5000? I tried to google it, but nothing useful came up.

@cskocsis I would first determine which IP it is attempting to listen on as it could be one of 3 addresses. I don't use this app but I suspect you can configure which address it listens on. The issue may be that it is trying to bind on the 0.0.0.0 address (listen on all IP) and is failing on one of the interfaces which may not be the one you want to use.
