<![CDATA[Bedrock server not opening any ports]]>I'm trying to install a bedrock server but I can't seem to connect to it.

When I port scan the cloudron server, I can see that 19132 is not opened.

What can I do to try and debug this?

You should not run that from inside the docker image but on the root system connected with ssh.

and the enable-lan-visibility settings

Is that a router setting or a bedrock server setting?

So running netstat -tulpen | grep -i 19132 from inside the docker image does return the expected results. netstat is not installed on Ubuntu by default so I couldn't try that on the host cloudron server (I'm wary of touching anything package-wise on the machine running cloudron because I don't want to mess up any dependencies).

nmap -sU -p 19132 my.cloudron.dev was interesting because it pretty much returns open|filtered on any port when using the lan address of the server but then returns correct open/closed when using the internet facing address of the server (which makes sense because it's going thru my router that way and that's where the port forwarding is).

Anyway, turns out that in my case it was a combination of IPv6 issues (tried to forward 19133 too but never got it working when the game was connecting via IPv6. Ipv4 works fine so I made my DNS entry by IPv4 only) and the enable-lan-visibility settings.

That second part looks like it needs to be enabled even if you're connecting to the server from outside the lan. Maybe I'm mis-understanding the purpose of that setting but basically with it off I couldn't get any connections going.

Let me try the netstat command from inside the app and see what that does for me. I'll post the app's log here if I can't find anything wrong.

I was unable to reproduce your issue.
Both nmap from external and netstat from internal showed the ports are open:

nmap -sU -p 19132 my.cloudron.dev
PORT      STATE         SERVICE
19132/udp open|filtered unknown
# from inside the Cloudron server
netstat -tulpen | grep -i 19132
udp        0      0 0.0.0.0:19132           0.0.0.0:*                           0          74015751   3966697/dockerd   
udp6       0      0 :::19132                :::*                                0          74015752   3966697/dockerd
