It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

hello @mascimax

I suppose on env change you are recreating the new container, that’s why everything got deleted.

hi, how to avoid this?

Well… do not edit the ENV’s or create a persistent storage :slight_smile:

To keep all your workflows and n8n configuration, you will need a database on the separate instance. Plus, it’s good to keep the n8n configuration on the external volume, that you can mount to the container on startup.

Initializing n8n process
Error: There was an error initializing DB
Error: connect ECONNREFUSED 127.0.0.1:3306

The message says the n8n can’t reach the DB instance on port 3306. If you have a separate instance with a DB, then it should have a different IP. 127.0.0.1 means it is located within the n8n instance
