What's Wrong?

Running claude code within anthropic repo devcontainer.

Running claude update fail to fetch update because of firewall. Using googleapis with rotating IP makes adding the domain to whitelist unpractical. Consider hosting the updates on a private server or updating the firewall to support domain whitelist instead of IP.
