<!-- Greeting --> Hey, @gabrielxfs! I'm here to help you with any bugs, questions, or contributions you have related to Superset. Let's work together to solve this issue! <!-- Answer --> The error you're encountering seems to be related to DNS resolution issues when Superset 4.1.1 tries to connect to Redis. Here are a few steps you can take to troubleshoot and potentially resolve this issue: 1. **Check DNS Configuration**: Ensure that the DNS settings in your environment are correctly configured. The error suggests that the DNS resolution is timing out, which could be due to incorrect DNS server settings or network issues. 2. **Verify Redis Hostname**: Double-check the hostname `redis.superset.internal` used in your configuration. Ensure that it is resolvable from within the Docker container running Superset. You can test this by executing a DNS lookup command inside the container. 3. **Network Configuration**: Make sure that the network configuration allows the Superset container to access the Redis server. This includes checking firewall rules, network policies, and ensuring that both services are on the same network or that there is proper routing between them. 4. **Use IP Address**: As a temporary workaround, try using the IP address of the Redis server instead of the hostname in your `CACHE_REDIS_URL` configuration. This can help determine if the issue is strictly DNS-related. 5. **Increase DNS Timeout**: If possible, increase the DNS resolution timeout settings in your environment to see if it alleviates the issue. 6. **Review Eventlet and DNS Libraries**: The stack trace indicates the use of `eventlet` and `dns.resolver`. Ensure these libraries are up-to-date, as there might be bug fixes or improvements in newer versions that address DNS resolution issues. If these steps do not resolve the issue, consider reviewing the network and DNS configurations in your deployment environment for any anomalies or misconfigurations. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
