No Server Errors in Logs but can't connect

[Tslinux]

Hello,
I have a problem with my ts3 server. I run a debian 32bit vps and installed the appropriate server version.
I start the server and this is in the logs:
0.log

When I now want to connect to the server this is what the client sees:

You probably have problem with firewall. Check iptable.

You probably have problem with firewall. Check iptable.

Thank you. It was the iptable firewall.
How I solved the problem.
1. Check if the server is Listening.
netstat -npl and look if you find this
udp 0 0 0.0.0.0:9987 0.0.0.0:*
2. Edit /etc/init.d/firewall
and add

iptables -A INPUT -i $device -m state --state NEW -p tcp --dport 30033 -j ACCEPT
iptables -A INPUT -i $device -m state --state NEW -p tcp --dport 10011 -j ACCEPT
iptables -A INPUT -i $device -m state --state NEW -p udp --dport 9987 -j ACCEPT

save the file and
/etc/init.d/firewall restart
3. Ts3 server should now accept connections
