Description Of Issue
I am a new user (sadly joined the trial a few hours before the black friday offer…), so I am trying to understand if Roon is for me for the next 2 weeks.
It works great with my Ipad, my Iphone, and all my computers, but I have big issues with my Android phone.
At first I was not able to connect, but reading the forum and entering as ip 255.255.255.255 I was able to connect to the server, but it keeps disconnecting.
Even if it reconnects in few seconds it makes the interface unusable. For example I am scrolling the tracks of an album, and I can’t click to them as it keeps disconnecting.
If I try to play a music (a random un as I can’t reach the one I would like to hear), and try to play it on my phone, usually it plays for a few seconds and then get disconnected. If I have some luck it could be 30-45 seconds.
From my firewall logs I see a lot of IPv6 multicast calls that got blocked to ip ff02::16. It is correct that they are blocked as I don’t have IPv6 and in my lan I don’t have any IPv6 DHCP server.
The phone anyway creates alone it’s IPv6 address (like my server and my computers).
I tried to fix the issue disabling IPv6 on the server and seems it helped a little but it is still driving me crazy with all those disconnections.
To do that I run the following commands on the server:
$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
I was not able to find any way to disable IPv6 on the phone or on the android app, perhaps this would fix the issue completely.
Thank you in advance for any help!
