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 v2.1.238

Blocked artifact asset downloads now name the host to allow

Use it now
Useful3 Signal2
Artifacts

Blocked artifact downloads now tell you to allow *.frame.claudeusercontent.com in your network settings.

What

When fetching an image or file attached to an artifact is blocked by network egress rules, the error now says which frame host was refused and tells you to allow *.frame.claudeusercontent.com (and its staging variant) in your sandbox or desktop app network settings.

Details
  • Three distinct failures are reported: blocked by egress policy, denied, and refused by the proxy.
  • The message makes clear that access to the artifact itself is unaffected.
Evidence

so the asset cannot be fetched (access to the artifact itself is fine)

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