Hi @garywilson4 - can you share the node-red log output from the server side?

Perhaps the browser cache is still using bits from node-red 0.18.x? Try either clearing your browser's cache, or forcing a full reload using shift F5 -- maybe?

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

The key line for why it isn't starting is : Error: dns service error: name conflict
I'm guessing you use node-red-contrib-homekit?
See https://github.com/mschm/node-red-contrib-homekit/issues/48

But you might want to open a new issue given these lines:

20 Sep 14:26:27 - [warn] nodes/core/io/lib/mqtt.js is deprecated and will be removed in a future release of Nod e-RED. Please report this usage to the Node-RED mailing list.

Well thats what the second message says to do...
I've never seen that message before!

Back on the home kit issue, that link suggests some things that might resolve the issue.

If it’s that node triggering that message then really the issue needs to be raised against it, as it must be quite out of date.

Then the Warn message needs amending (and not just the typo)

Yeah. Noted

The mqtt files its warning about are gone in 0.20. We've been warning they are deprecated for about 2 years now. I think that's enough time to be fair.

As an alternative have a look at: homebridge-mqtt

You can use the core mqtt in and mqtt out nodes.
