2 HA-Bridge instances: UpnpListener encountered an error sending upnp notify packet. IP: 239.255.255.250 with message: Operation not permitted

Hi,

as stated in issue #736, I need to run 2 HA-Bridge instances on the same Raspi2.
However, upon doing so, I now get my log flooded with this message that I didn't have before:

UpnpListener encountered an error sending upnp notify packet. IP: 239.255.255.250 with message: Operation not permitted

I use 2 different home-dirs, thus running 2 different config files, 1 for each instance.
My further settings are:

• Raspi2, Raspian Jessie, HA-Bridge 4.5.6
• Use UPNP Address Interface Only = FALSE
• UPNP Strict Handling = FALSE
• Port for Webinterface, instance 1: 81
• UPNP-Port, instance 1: 50001
• Port for Webinterface, instance 2: 82
• UPNP-Port, instance 2: 50002
• local IP adress of my Raspi: 192.168.178.220

Thanks for your help.
Heiko

Will take a look as that should not happen.

Thanks! I really hope you can fix this!

I tried some other things today - not successful though.

• I bound a 2nd IP-Address to my Raspi, assigning the new IP to the 2nd instance (in the HA-Bride Webinterface config). Error still occurs.
• I added 2 iptables rules. Error still occurs
  iptables -I INPUT -p ALL -s 239.255.255.250/24 -j ACCEPT iptables -I OUTPUT -p ALL -d 239.255.255.250/24 -j ACCEPT

As soon as I stop one of the two instances, the error message stops!

I think I may need to have a bind on the upnp interface if it is specified.

Despite the error messages in the log, I now have 3 instances running (24/32/31 devices).
If I put all of these devides into 1 habridge, Alexa completely messes up recognizing any voice commands.
Just right now I tried adding a 4th instance, however, now Alexa also messes completely up.
A random small number of devices of any of the 4 virtual bridges is now not found by device discovery.
Any idea why that is happening?

I have updated the upnp socket implementation to be on only one socket for the multicast responses.
