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.

First go into into your .node-red directory and run  
`npm rebuild`  
Then use manage palette to check all your nodes are on the latest versions.

To expand on Colin's response, many major version changes of node.js come with an update C++ compiler and libraries and so any binary libraries included in packages have to be recompiled. That is what the `npm rebuild` command will do.
