Fix ChatGPT OAuth issues
Use this guide when connecting ChatGPT Plus or ChatGPT Pro in Settings → Providers → OpenAI and the OAuth flow fails for reasons other than the disabled Continue button.
For the specific device code authorization error, see Enable device code authorization for Codex—that fix applies first for most Plus/Pro connection failures.
Steps
- Confirm you sign in with the ChatGPT account that has the subscription you intend to use.
- Complete device code authorization if Continue is disabled on the consent screen.
- In Orion, disconnect and use Connect ChatGPT Plus / Pro again.
- Allow the OAuth pop-up window if your browser blocks it (same as PDF pop-up settings).
- If the flow still fails, try an OpenAI API key instead under the same provider section for pay-per-token access.
When you need this
- OAuth window closes without connecting
- Error after email verification but before Orion shows connected
- Subscription account differs from the one used in ChatGPT web
Notes
- ChatGPT OAuth credentials stay in browser storage only—not in
settings.json. - OpenAI may change consent screen labels over time; search settings for Codex or device if menu paths differ.
