What

When Claude Code runs in a cloud sandbox, which is an isolated environment, its network traffic goes through a proxy. That proxy changed in several ways:

  • It can now use a local relay connection.
  • After a relay failure it logs a notice that it is holding off before trying again.
  • It counts certificate authority (CA) blocks it cut or could not judge. CA certificates are what programs use to decide which connections to trust.
  • It writes the CA certificate store for Java programs more strictly.
  • A file upload that fails with a transport error is sent once more on a fresh connection.
Why

Networking inside cloud sandboxes should fail less often, and a single dropped upload no longer fails outright.
