@Marvin I am running self hosted prefect with work-pool type as docker. in my worker logs, the run crashes with error

httpx.ConnectError: [Errno -2] Name or service not known

, what could be wrong

The error

httpx.ConnectError: [Errno -2] Name or service not known

typically indicates a DNS resolution issue, where the service name or URL cannot be resolved to an IP address. Here are some steps you can take to troubleshoot this problem: 1. Check Network Configuration: Ensure that your Docker environment has access to the network where the Prefect API or other services are hosted. You might need to configure Docker's network settings. 2. Environment Variables: If you are using proxies, make sure the

HTTPS_PROXY

and

SSL_CERT_FILE

environment variables are correctly set in your execution environment. This can affect how HTTP requests are routed. 3. Service URLs: Verify that the service URLs you are trying to connect to are correct and accessible from within your Docker container. This includes checking any DNS settings or hostnames. 4. Prefect Configuration: Ensure that your Prefect configuration is set up correctly. You can use the

prefect config view

command to check your current configuration settings. 5. Work Pool and Worker Setup: Make sure your work pool is set up correctly and that the worker is running and able to communicate with the Prefect API. You can find more information on setting up Docker work pools in the Prefect documentation. If you continue to experience issues, you might want to check if there are any network policies or firewalls blocking the connection.
