I installed this snapcast_armhf-debian-bookworm-1184cf1db39e6106a3442ae92e92f5b872ac1b62's snapclient binary

So the snapclient is connecting with a IPv6 address fd5e.... to the snapserver and the snapserver is not listening on IPv6 by default.
I configured IPv6 support for snapserver (v0.28.0 beta1) and the client can now connect successfully.

@badaix What do you suggest to get the snapclient to prefer IPv4 over IPv6 when both IPs are resolved ?

I don't know what the best practice is to give a hint to a client on what kind of IP address to resolve, but I think it doesn't make sense to not try other resolved addresses, if the first one is not working.
So I've added a loop through all IP addresses, in case a connection attempt failed.
You can find packages here:

Both resolved IPs are tried and eventually one succeeds.
