Where n8n ssl files stored and how to renew n8n site ssl?

I follow this instruction https://docs.n8n.io/reference/server-setup.html#example-setup-with-docker-compose to install n8n but don’t know where n8n ssl files stored and how to renew n8n site ssl.

If I want to use custom ssl file, can I follow this instructions? https://docs.n8n.io/reference/configuration.html#ssl

```
export N8N_PROTOCOL=https
export N8N_SSL_KEY=/data/certs/server.key
export N8N_SSL_CERT=/data/certs/server.pem
```

n8n does not store SSL certs anywhere. Traefik is taking care of all of that. It will save them in a subfolder of ${DATA_FOLDER}/letsencrypt. It should normally actually also auto-renew that certs before they expire.

Yes, you can use what you wrote above to use custom certs.
