Node RED OPC UA Server error

General

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.

Are you running node-red as a service or directly from command line?

Where is node-red installed - same computer as the file or is node-red installed on a remote server?

Does the account running node-red? Have permissions to read that file?

Hi
Yes it is on the same computer. The strange thing is the same file were working until June then now I have this errors. On my VM it is working fine. The permissions are inside. My be I can share with you the flow ?

D:\HMI\.node-red\

Your node-red is installed in D, can it access C volume?

The node label show /home/opc/global.json but it should be C:/home/opc/global.json or D:/home/opc/global.json.

yes i have the access in D and also the path is configured for D:
