Need help connecting to Bedrock on LAN

[benneic]

I've just done a fresh install of MC Bedrock and configured with default settings. But I can not seems to connect with it from the iPad app while connected on the same network/subnet.

App Title and Version: Minecraft Bedrock 1.21.80.3
App ID: 613cef5b-96ff-489d-a8bf-c1f9c07cd4b4
Package Version: net.minecraft.bedrock.cloudronapp@2.35.5
Installed At: 3:59 PM
Last Updated: Never

MC Bedrock Server console shows:

IPv4 supported, port: 19132: Used for gameplay and LAN discovery
IPv6 supported, port: 19133: Used for gameplay
Server started.

Scaning the server & port from my computer:

benneic@MacBookPro ~ % nmap -p 19132 192.168.1.100
Starting Nmap 7.95 ( https://nmap.org ) at 2025-05-15 16:38 AEST
Nmap scan report for # (192.168.1.100)
Host is up (0.012s latency).

PORT      STATE  SERVICE
19132/tcp closed unknown

Nmap done: 1 IP address (1 host up) scanned in 0.11 seconds

Scaning listening ports on my server host (192.168.1.100):

benneic@chopsticks:~$ sudo netstat -l -p --numeric-ports | grep 19132
tcp        0      0 0.0.0.0:19132           0.0.0.0:*               LISTEN      847/dockerd         
tcp6       0      0 [::]:19132              [::]:*                  LISTEN      847/dockerd         
udp        0      0 0.0.0.0:19132           0.0.0.0:*                           847/dockerd         
udp6       0      0 [::]:19132              [::]:*                              847/dockerd  

Scanning listening ports inside the MC Bedrock docker container:

root@613cef5b-96ff-489d-a8bf-c1f9c07cd4b4:/app/pkg# sudo netstat -l -p --numeric-ports | grep 19132
udp        0      0 0.0.0.0:19132           0.0.0.0:*                           -                  

I am surprised there is not a tcp socket listening inside the docker host.

As far as the server console and logs are concerned it looks like it is running:

What am I missing here?

Does your server have any extra firewall in front? Assuming you run this server at home, how did you expose that on the internet and can you maybe try to connect from the client with the public ip?

@benneic BDS uses UDP and not TCP . The TCP configuration in package is misleading - https://git.cloudron.io/packages/minecraft-bedrock-app/-/merge_requests/23 removes it.

Try udp scan -

$ sudo nmap -sU -p 19132 116.203.196.36

Solution was to connect from iPad to server using the FQDN pointing to the public IP of Cloudron.

Unclear why I couldnt connect via private IP, but I was using local DNS pointing the FQDN to the private IP, so I switched that to the public ip. I think that is what fixed it.

@girish thanks for the tip on the UDP scan, port was open via UDP on private IP.
