Setup script failed with exit code 22.

Script output:

curl: (22) The requested URL returned error: 503


Edit your environment's setup script and start a new session.

I do not believe this 503 is from the Determinate Nix infrastructure, as I have used this locally, on clouds, and on other AI remote backends; this only happens on Claude Code remote environments and has consistently failed for weeks now.
