I have inserted Node-red-contrib-persist into a recent flow running the most current version of node-red. After a Deploy, the dashboard can no longer be displayed. Both Microsoft Edge and Google Chrome report “Connection Refused.” This has occurred on two different Win11 systems and RaspberryPI. The only way out of this problem is to replace node-red and the local node-red folder.
What do the logs say?
I am unfamiliar with the logs. Can you provide me direction?
On Raspberry Pi they can be found in /var/log/
On Windows it depends on how you are starting Node-RED but they should look something like this on startup:

Do you have auth turned on for the Editor? Because the API it defines requires "persist.write" permission:
Thanks all for your feedback. Currently I am testing the flows on a Win11 node-red installation. I made sure the target directory has R/W permissions for persists nodes..
The persists nodes appears to work properly in a test flow. I have built a couple of flows that appear to work without persists nodes. Once I install the persists nodes and integrate them with my existing flows and deploy, connection is lost. The console comes up with extensive errors. I have to remove the .node-red directory and replace it with one where there are no persist nodes to deploy successfully. I am still chasing the issue.
Could you copy and paste them here?

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've had this error message with the persist node in the past. To fix it you edit this file;
"C:\Users\srado.node-red\node_modules\node-red-contrib-persist\persist.js:
and change the 2 occurrences of "nodes-started" to "flows:started"
you will probably have restart node-red again afterwards.
the image below shows the code changes. Left window shows the correct code.
Thank you for the assist. I had already discovered this solution.
