Wont Connect anymore
Ben,
Thanks for your email reply,
I have Node Red and cant get the Alexa Home skill to connect anymore but was working really well. Continues to say Re-connecting now and also doesn't show any devices in the node red Alexa Home Node setup?
I have checked all my credentials and the linking works perfectly? It must be something simple as was working perfectly?
Any ideas? I can give you my username or any other info if that helps?
Nick Clay - [email protected]
Continuous reconnecting implies either the username/password are wrong or you have 2 instances connected (you can only have one and there should only be a single config node shared between all device nodes)
Please share the node-red logs and the username
Thanks user is Clayhome, are you able to help me get the node red logs or is this it?

I can use the same Username and password entered into the Skill URL website ok?
I do have the "node-red-contrib-alexa-remote2" running ok as well? in node red?
I need more logs than that, what you've given never started the flows because the original version is still running.
The other node should not matter, the logs would have shown if there was an internal node name clash.
From the burger menu in the to right hand corner select configuration nodes and double check that you only have 1 instance of the node with the name matching your username.
Also double check that you do not have any old versions of Node-RED running on other machines configured with the node (even just the configuration node).
I'll check the broker logs for that username later when I get back to confirm it's multiple instances.
Also it would be useful to get a section of logs that covers a time when you press the refresh button next to the list of devices drop down.
Since midnight UTC there has only been one instance connected to the broker. It connected at 13:13 UTC and disconncedted at 13:31 UTC.
I need to see the NR logs from the running instance that is trying to connect (may be run the node-red-logs command

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.

i have stopped my other node red at home just encase, but still not working - but it did connect for short time?
All I can suggest is find the alexa.js file under node_modules/node-red-alexa-home-skill and take the // off the start of line 102
So it reads as follows
node.client.on('error', function (err){
console.log(err);
node.setStatus({text: 'disconnected', shape: 'dot', fill:'red'});
node.error(err);
});
}
This should print some more error messages to the logs (but they should already be showing up in the debug sidebar)
I've seen it connect once more today
