Umurmur OpenWrt 18.06.1 r7258-5eb055306f

I tried to install the Umurmur server .. but it seems not to start, the client does not connect ... you can tell me if this version of openwrt supports Umurmur
Thank you very much

It appears to exist in OpenWrt, therefore it's supported: https://openwrt.org/docs/guide-user/services/voip/umurmur

Did you enable it in the configs?

Thanks for your answer

# Channel tree definition:
# Root channel must always be defined first.
# If a channel has a parent, the parent must be defined before the child channel(s).
channels = ( {
	 name = "Root";
	 parent = "";
	 description = "Root channel. No entry.";
	 noenter = true;
	 },
	 {
	 name = "Lobby";
	 parent = "Root";
	 description = "Lobby channel";
	 },
	 {
	 name = "Red team";
	 parent = "Lobby";
	 description = "The Red team channel";
     # password = "redpw";
	 },
	 {
	 name = "Blue team";
	 parent = "Lobby";
	 description = "The Blue team channel";
     # password = "bluepw";
	 }
);
# Channel links configuration.
channel_links = ( {
	 source = "Lobby";
	 destination = "Red team";
	 },
	 {
	 source = "Lobby";
	 destination = "Blue team";
	 }
);

# The channel in which users will appear in when connecting.
# Note that default channel can't have 'noenter = true' or password set
default_channel = "Lobby";

Unfortunately the client tells me connection failed

How can I tell if the server is actually running?
Thank you very much
