If the DSQA comes up empty, we need to take it one step at a time and ensure it in the following order:

--------------------
PubsubServer routes:
--------------------
the client (both publisher and subscriber) need to connect tot he rigth pubsubserver. There are 3 days to do this:
1. Bring up a DSQA and check the title bar, it should be tag:regExp: PubSunRoute
the ip and port matter, the prefix is just fo the human eye.
2. Run the stream pss_routes().
It will give a row per tag reg exp vs the pss route (pss == pubsub server0)
3. Check the clirnt logs for:
PubSubRouter.get_sub_url_for_tag tag: and PubSubRouter.get_pub_url_for_tag tag:

-------------------
Connection Attempt:
-------------------
Check the pss logs for:
"AsyncTCPConnectionAcceptor_AsyncWrapper.cons started on port:"
Make sure it is listening to the correct port

On the client, make sure it is attemping to connect to the right pss
"AsyncTCPConnector_AsyncWrapper.connect_to server:"


------------------------------------
Successful connection establishment:
------------------------------------

On pss, a successful connection should result in the log:
"calling onConnection now"
The whole log is 
Log.Gen.info($"AsyncTCPConnectionAcceptor_AsyncWrapper._begin_accepting port: {_accept_port}, new connection, self: {conn.get_self_address()} peer: {conn.get_peer_address()} calling onConnection now");

On the client, a successful connection should result in the log:
"AsyncTCPConnector_AsyncWrapper._connect_to new connection,"


------------------------------------
Successful message sent from client:
------------------------------------
"AsyncTCPConnection_AsyncWrapper._send_fixed_size_msg sent"

--------------------------------------
Successful message received on client:
--------------------------------------
"AsyncTCPConnection_AsyncWrapper._read_fixed_size_msg read"


pss's send/receive is the same log, since it uses the same class AsyncTCPConnection_AsyncWrapper
---------------------------------
Successful message sent from pss:
---------------------------------
"AsyncTCPConnection_AsyncWrapper._send_fixed_size_msg sent"

-----------------------------------
Successful message received on pss:
-----------------------------------
"AsyncTCPConnection_AsyncWrapper._read_fixed_size_msg read"
