The request hangs for ~44 seconds before being cancelled with: "net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)" Notably, in the same terraform init run: - hashicorp/google v5.40.0 resolves and installs successfully - registry.terraform.io/terraform-google-modules/vm/google 12.1.0 downloads successfully - All other external network calls succeed The failure is specific to the hashicorp/google-beta version query endpoint and resolves on retry, confirming it is intermittent registry-side latency and not a persistent network issue on our end. ### Steps to Reproduce 1. Create versions.tf with both hashicorp/google and hashicorp/google-beta as required providers: required_providers { google = { source = "hashicorp/google" version = ">= 4.48.0, ~> 5.40.0, < 7.0.0" } google-beta = { source = "hashicorp/google-beta" version = ">= 4.48.0, >= 5.36.0, 6.40.0, < 7.0.0" } } 2. Run terraform init on a GCP-hosted Linux amd64 runner 3. Terraform resolves both providers in parallel 4. Observe intermittently (~10-20% of runs): - hashicorp/google resolves successfully - hashicorp/google-beta times out after ~44 seconds - terraform init exits with code 1 5. Re-run terraform init — succeeds on retry confirming transient issue ### Additional Context - Terraform version : 1.8.5 - Runner OS : Linux amd64 - Runner type : GCP-hosted, self-hosted, ephemeral - Terragrunt : yes - Frequency : Intermittent, ~10-20% of runs - First observed : May 18, 2026 - Resolves on retry : Yes Timeline from failed run (May 18, 2026 04:50 UTC): 04:50:33 google-beta version query started 04:50:33 google version query started (parallel) 04:50:54 google query completed (~21s) 04:51:16 google v5.40.0 installed successfully 04:51:17 google-beta FAILED after ~44s — 2 attempts exhausted ### References _No response_ ### Generative AI / LLM assisted development? _No response_
