Hi @backwind1233,

The error you're seeing here is from the azurerm provider, not from Terraform, but unfortunately it is likely not something the provider can directly control either. There is an open issue with WSL regarding their resolver responses here, which appears to be the cause of the problem you are seeing.

Since there's nothing we can change within Terraform to avoid the problem, I'm going to close this issue. There may be a workaround coming in the go1.18 release, but that would require a new release of the provider to implement.

Thanks!
