not sure what the reason is. I have homebridge running on the same machine which also uses avahi - can that be somehow the reason?

When do you receive this? Right at launch or after starting a stream? It advertises on port 5000 which is the default AirPlay port. You don't happen to have other AirPlay services running on this machine on port 5000 do you?

[snizzleorg]

yes, right at launch. I do have forked-daapd running but it uses port 3689. Also librespot which uses 5353 for mdns.
Any way I can find out if anything is bound to 5000

[noelhibbard]

I kind of doubt it's a port conflict to be honest because it is saying connection reset. If it was a port conflict I would have expected it to say something like port in use.

To list all the ports that are in use and what process are associated, use this command:
netstat -lp

[snizzleorg]

nope. no port conflict.

The error occurs right at launch....

I can second this behaviour...

only I start it via systemd and after a few seconds it is exiting:

Is there anything that could help for finding the problem, link log or so?

best,

Got everything Sorted. Reinstalled raspbian (Stretch), installed node v4 via nodesource and everything works like a charm, except Audio gets pauses Every 20-30 seconds...

[noelhibbard]

@Goeste , the RPi just doesn't have the CPU power to handle node-airplayhub. I originally ran mine on an Intel Atom N230 and it had drops if I ran anything more than 2 zones at a time. I moved it over to an Intel i5 and now it works perfect with all 5 of my zones running at a time.

[Goeste]

@noelhibbard , would an enhancement with the node cluster module help, to balance the node-airplayhub load (to eliminate audio-drops? link
