Node red won't deploy changed nodes

**garywilson4** · September 19, 2018, 2:33pm

Hi i updated my node red to 0.19.4 now it won't deploy saying lost connection to server I'm a complete n00b at this so be patient with me

**knolleary** · September 19, 2018, 2:35pm

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

**shrickus** · September 19, 2018, 6:22pm

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?

**garywilson4** · September 20, 2018, 1:28pm

where does it store the log output? rpi running raspian i think

Your flow credentials file is encrypted using a system-generated key.

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.

this is what comes up on the cosole screen

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.

**garywilson4** · September 20, 2018, 5:18pm

yes homekit used
thanks for help open new issue on this forum for that warning?

**ukmoose** · September 20, 2018, 5:30pm

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.

**garywilson4** · September 20, 2018, 6:13pm

resolved this issue by removing homekit but will look further into it as i do want homekit

**dceejay** · September 20, 2018, 6:33pm

If it’s that node triggering that message then really the issue needs to be raised against it, as it must be quite out of date.

**ukmoose** · September 20, 2018, 6:38pm

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

**dceejay** · September 20, 2018, 6:59pm

Yeah. Noted

**knolleary** · September 20, 2018, 7:11pm

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.

**cflurin** · September 20, 2018, 7:33pm

As an alternative have a look at: homebridge-mqtt

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