@ancient-wolf-19325 I'm getting this error when trying to register a pipeline, though the url is working fine in a browser • Failed with Unknown Exception <class 'RuntimeError'> Reason: Failed to get signed url for fast • details = "DNS resolution failed for <domain>: C-ares status is not ARES_SUCCESS

The error you're encountering is related to DNS resolution issues with the C-ares DNS resolver used by the Python gRPC client. This is a known issue and can be resolved by switching the DNS resolver to the OS's native DNS resolver. To fix this, set the environment variable

GRPC_DNS_RESOLVER

to

native

. This forces the gRPC client to use the native DNS resolver instead of C-ares.

export GRPC_DNS_RESOLVER=native

After setting this environment variable, try registering your pipeline again. Would you like more details on this solution? Sources: - GitHub Issue #2884 - Flyte Discussion 👍 1 button 👎 0 button 💡 Hint: Mention @ancient-wolf-19325 in the thread for followups.
