Codex Desktop login loop on macOS while CLI works; auth refresh drops token after 401

Summary

Codex CLI works normally with ChatGPT authentication, but Codex Desktop on macOS enters a login loop whenever I open/select a conversation.

The Desktop app initially detects the authenticated ChatGPT account successfully. However, when a conversation is opened, a backend request returns HTTP 401. The Desktop then attempts to refresh authentication, but the auth state changes to:

authMethod=chatgpt
hasToken=false
nullReason=auth_token_missing
refreshToken=true
tokenExpiryState=missing

After that, subsequent requests are sent without an access token and return 401, causing the Desktop app to ask me to log in again.

Relevant logs

desktop_fetch_auth_401 hadToken=true ... willRetry=true

app_server_connection.auth_status_result
authMethod=chatgpt
hasToken=false
nullReason=auth_token_missing
refreshToken=true
tokenExpiryState=missing

chatgpt-account-lookup
authenticatedAccountPresent=false
failureType=account_info_token_unavailable

Missing valid access token or actor biscuit

desktop_fetch_auth_401
hadToken=false
skipRetryReason=no_token_attached

Earlier in the same run, the Desktop app successfully detected the authenticated account:

chatgpt-account-lookup ... authenticatedAccountPresent=true authMethod=chatgpt ... result=succeeded

The failure then occurs when opening/selecting a conversation.

Expected behavior

Codex Desktop should reuse or successfully refresh the valid ChatGPT authentication state, as Codex CLI does.

Actual behavior

Desktop starts normally and initially recognizes the authenticated account, but opening/selecting a conversation causes authentication to fail and the app asks me to log in again.

Troubleshooting already performed

• Upgraded Codex CLI from an older version; CLI now works normally
• Verified codex login status reports ChatGPT authentication
• Verified ~/.codex/auth.json exists and has correct permissions
• Reset Codex Desktop Application Support and cache
• Reinstalled/updated Codex Desktop
• Verified CODEX_HOME is not overridden
• Verified no CODEX_ACCESS_TOKEN, OPENAI_API_KEY, OPENAI_BASE_URL, or related environment overrides exist
• Issue still reproduces with a clean Desktop profile while CLI continues to work

Environment

• macOS
• ChatGPT authentication
• Codex CLI: working normally
• Codex Desktop: login loop when opening/selecting a conversation

Failure sequence

Desktop starts
  -> authenticated account is detected
  -> open/select a conversation
  -> request sent with token (`hadToken=true`)
  -> backend responds 401
  -> Desktop attempts refresh
  -> auth becomes `hasToken=false`, `auth_token_missing`, `refreshToken=true`
  -> subsequent requests are sent without a token
  -> login prompt appears again
