Check out #527 ?

I had the same issue but didn't find anything how to solve it. At the end I figured out as I run homebridge inside of a docker with the commandline including --net=host that the Bonjour service port 5353 was already occupied by some other process. You can check if the port is already taken by some process with

netstat -anp | grep 5353

This will list something like:

`
[~] # netstat -anp | grep 5353

netstat: /proc/net/tcp6: No such file or directory
udp 533760 0 0.0.0.0:5353 0.0.0.0:* 13315/python
udp 533760 0 0.0.0.0:5353 0.0.0.0:* 13315/python
udp 533760 0 0.0.0.0:5353 0.0.0.0:* 13315/python
udp 533760 0 0.0.0.0:5353 0.0.0.0:* 13315/python
`

the 13315 is the pid which you then can check what the process is.

can you let me know how you figured out it was the port. i am getting the same error and i disabled the avahi demon running on the nas but i still get this error

[/share/Docker/homebridge] # netstat -plunt | grep 5353
netstat: /proc/net/tcp6: No such file or directory
netstat: /proc/net/udp6: No such file or directory

i had to log into the container to run the avahi manually by giving following command.. in case its helpful to anyone else

/etc/init.d/dbus start
avahi-daemon --debug --no-drop-root
