Management Center restarting broker?

wanted to clear that do I need to do anything chown ? because I’ve not done it… if yes How can I do>

It looks like you missed changing your configuration. You have this:

listener 8883
certfile /root/cedalo_platform/mosquitto/config/certificates/chain.pem
keyfile /root/cedalo_platform/mosquitto/config/certificates/cert.pem

Instead of this:

Note the fullchain instead of chain as well.

oops My bad…

Thank you so much Roger for helping me out. I got connected with SSL.

one more thing I notice is that I’m getting error on console like this. what is that about? will this cause in future?

I thing my cedalo Management is trying to connect this broker. Because I’m not able to connect management with broker.

Great, I’m glad you’ve got it working.

This almost certainly means you have a client trying to connect to port 8883 that is not using TLS.

Can you help me on that… I tried SSL v1 to V3 and TLS V1 to V3 from Mqtt.fx, Same problem

also I want websocket so how can i add that?

I tried to put port for websocket
image
and

CEDALO_MC_BROKER_URL: mqtts://mydomain.com:8883

not able to connect.

In your configuration you will need a websockets listener:

listener 9000
protocol websockets

I do not believe that your mqtt.fx connection is using TLS. Try mosquitto_sub instead: mosquitto_sub -h <your host> -p 8883 -t '$SYS/# -v

Thank you Roger. It is running now. I accidently put client id in management platform. so without that client id it will not connect. so now I left it blank.

and one more thing can I give my certificate for management platform so it can be secure??

again Thank you so much roger.

Sorry I forgot to reply to the last part - the management centre doesn’t support certificates at the moment. You could raise this as an issue at Issues · cedalo/management-center · GitHub if you like.
