Simple Fix for Binary 404 Errors in N8n (Docker or Self-hosted)
Add the following lines to your .env file or Docker environment config:
N8N_BINARY_DATA_MODE=filesystem
N8N_DEFAULT_BINARY_DATA_MODE=filesystem
N8N_EXECUTIONS_PROCESS=own
Then restart N8n.
This ensures:
*Binary files are stored properly on disk
*Workflows can access the files after execution
*404 errors when downloading files (like images/videos) are avoided
That’s it! This fix works for Docker, N8n cloud (if supported), or self-hosted setups.
