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 v2.1.248

Two distinct OAuth refresh failures with recovery text

You'll notice
Useful4 Signal2
Auth

Login refresh failures now say whether to run /login or that another session holds the lock.

/login
What

A failed login-token refresh now says which failure it was: the refresh token is no longer valid, in which case it tells you to run /login, or another Claude Code process is currently holding the refresh lock. This is mostly what you see when two sessions try to refresh credentials at the same time.

Evidence

OAuth access token could not be refreshed: another Claude Code process is holding the refresh lock

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