Server is not running

[raulus127]

I am trying to run an opc ua server with this json that I attached. It doesn't work for me. I've seen other threads on this forum but it seems like something else is happening. The error that appears is "Server node error on: error: "Server is not running". Can you help me please? Thank you so much!

pp.json

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 read in another thread that this error was solved by updating the version to v0.2.112. Will I have to do it or do I already have it updated? I downloaded the latest version from the page.

I expect you have some other troubles on your environment and most probably also inside the flow.
Can you attach flow file?
