DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.242

Proxied HTTPS connections verify the original hostname

Useful3 Signal2
Internals

Connections through an HTTPS proxy now verify the certificate against the host you asked for.

What

Connections made through an HTTPS proxy now check the server's certificate against the host you actually asked for, and for non-literal hostnames Claude Code resolves the address itself while still sending the original name for SNI and verification. Two new failure reasons cover a credentials file holding the gateway's TLS pin being a symlink or unreadable.

Details
  • symlinked credential files are not followed
  • applies to all proxied connections, with no setting to opt out
Evidence

"the credentials file that keeps the gateway's TLS pin is a symlink, which is not followed"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
