[SOLVED] node-red 'MQTT in' disconnected - svtgd - 01-30-2018

I had MQTT in and MQTT out nodes working in node-red - then last night they died - a  little red square and "disconnected" under the node. I've tried localhost:1883, 10.10.10.1:1883, running node red on the pi and on my connected laptop, starting and stopping mqtt, and reboots.

I revived my old cloudmqtt broker/freeboard.io and they are getting and displaying the mqtt data. 
Here are the /var/log/mosquitto/mosquitto.log  entries
1517338412: New connection from 127.0.0.1 on port 1883.             <--- this is cloudmqtt  umifqkims is username
1517338412: New client connected from 127.0.0.1 as                        @:vvXqbR:7USncFdC<@3q2qV@pkr_tMo6K\^3F8==MQl8WWKdWNLY6cigERMAp3G (c1, k60, umifqkims).   
1517338412: New connection from 10.10.10.1 on port 1883.         <-------------I think these  three are my MQTT in nodes 
1517338412: New connection from 192.168.1.20 on port 1883.                          trying to connect 
1517338417: New connection from 127.0.0.1 on port 1883.
1517338417: New client connected from 127.0.0.1 as 2_e5um2sBSf:2DUV[drtZ\THbvesmh1oOfd;Kg5MA[W3_lYAWS<ro`AX^gBBFCre (c1, k60, umifqkims).  

So - the data is there and getting out - just not getting into node-red. 

The 'websocket in' localhost:3000 node is connecting and receiving data and sending output to the dashboard. For a brief moment this morning the 'MQTT in' node connected, then it "Disconnected" again. 

Im in MQTT jail!   Sad

Ideas? How can I troubleshoot? 

Thx.

on the mqtt node server is the tab security set to what you have on the server?

Thanks Jim. That did it. 

I had commented out the allow_annonymous false entry in /etc/mosquitto/conf.d/openplotter.conf and was able to connect. I was going to add a note to the forum about that when I saw your note. 

I removed the comment and restarted and after entering the user/pass on the mqtt node security tab everything is working again.

I appreciate your help Jim!
