Hi, I’m facing issues with AWS STS on the instantiation of the aws provider. Some days (already more than once) receive error: rpc error: code = Unknown desc = unable to validate AWS credentials. Details: validating provider credentials: retrieving caller identity from STS: operation error STS: GetCallerIdentity, https response error StatusCode: 0, RequestID: , request send failed, Post “https://sts.eu-west-1.amazonaws.com/”: dial tcp: lookup sts.eu-west-1.amazonaws.com on [20018a07b3ff5001]53: no such host Make sure you have set your AWS region, e.g.

pulumi config set aws:region us-west-2

. By the way, already tested all the sets for the config available and ensured that aws cli is operational. Those anyone else is facing this issue? pulumi version v3.69.0. (also happening with v3.68.0)

53: no such host

This is a DNS error, ie: a local network issue
