I am Getting an XMPP Error and Not Sure How to Remedy

From: [Extensible Messaging and Presence Protocol (XMPP): Core](https://xmpp. /rfcs/rfc6120.html#streams-error-conditions) -
### 4.9.3.6. host-unknown

        The value of the 'to' attribute provided in the initial stream header does not correspond to an FQDN that is serviced by the receiving entity.

Host file looks something like:

127.0.0.1       localhost
XX.XXX.X.XX     meet.politea.us meet -- Local Domain
185.198.26.116  meet.politea.us meet -- Public Doman
127.0.0.1       localhost    meet.politea.us
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

ping “$(hostname)” returns:
PING meet.politea.us (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.039 ms
64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.063 ms
64 bytes from localhost (127.0.0.1): icmp_seq=3 ttl=64 time=0.045 ms
64 bytes from localhost (127.0.0.1): icmp_seq=4 ttl=64 time=0.045 ms

root@meet:/etc# echo 'yes, it is accessable' | nc -u meet.politea.us 10000
returns nothing.

jvb.log gives the following:

I can see something is terribly wrong, I need to know what I need to do to fix it.

Ports 10000, Prosody Port 5347, JVB_PORT=5275 are open.

Why do I get different results when running “netstat -tulip” and “csf --status”?

This what I see when running “netstat -tulpn” notice no port 10000:

This is what I get when I run “csf --status” notice port 10000 is listed, both tcp and udp:
