I think its working now. I made few other error like : with =

```auto
module.exports = {
    apps : [{
        name : "n8n",
        env: {
            N8N_BASIC_AUTH_ACTIVE:true,
            N8N_BASIC_AUTH_USER:"user",
            N8N_BASIC_AUTH_PASSWORD:"password",
            N8N_HOST:"sub.domain.com",
            WEBHOOK_URL:"https://sub.domain.com",
            GENERIC_TIMEZONE:"Europe/London",
            EXECUTIONS_TIMEOUT:3600,
            EXECUTIONS_TIMEOUT_MAX:7200
        }
    }]
}

```
