I have installed airbyte in a kubernetes cluster and connected to an external DB, running in the same cluster. Everything was working correctly, but when I stopped and restarted the cluster I received errors on the server pod, where temporal is unreachable

any idea what could cause this?

Based on the error logs you provided, it seems like the Airbyte server is unable to connect to the Temporal service. This could be due to a variety of reasons such as network issues, incorrect configuration, or the Temporal service not being ready yet. Here are a few steps you can take to troubleshoot this issue: 1. Check the status of the Temporal pod: Use the

kubectl get pods

command to check the status of all the pods. Make sure the Temporal pod is running and not in a crash loop. 2. Check the logs of the Temporal pod: Use the

kubectl logs <temporal-pod-name>

command to check the logs of the Temporal pod. This might give you more information about why the Temporal service is not reachable. 3. Check your network configuration: Make sure that the network policies and firewall rules in your Kubernetes cluster allow traffic between the Airbyte server and the Temporal service. 4. Check your Airbyte configuration: In the [Airbyte documentation](https://docs.airbyte.com/operator-guides/configuring-airbyte-db/), it is mentioned that you need to correctly set up the environment variables for the database connection. Make sure these are correctly configured. 5. Restart the Airbyte services: Sometimes, simply restarting the services can solve the issue. You can do this by deleting the deployments and reapplying them as mentioned in the [Airbyte upgrade documentation](https://docs.airbyte.com/operator-guides/upgrading-airbyte/). If none of these steps solve your issue, I would recommend reaching out to the Airbyte community on their [Slack channel](https://slack.airbyte.io/) or [creating an issue on GitHub](https://github.com/airbytehq/airbyte/issues/new?assignees=&labels=type%2Fbug&template=bug-report.md&title=).

I have already tried to use a new database, to no avail
