Summary
The Codex in-app browser can report that a page is offline during a user handoff for login, interrupting workflows where Codex opens a site and then waits for the user to authenticate manually.
Affected workflow
A Codex agent opens an arbitrary website in the in-app browser, reaches a login page, asks the user to log in manually, and then should wait until the user is authenticated before continuing. Instead, the in-app browser/page can show an offline banner during the login step.
Steps to reproduce
- In Codex desktop, ask Codex to open a website with a login flow in the in-app browser.
- Let Codex navigate to the login page and stop so the user can enter their login details manually.
- During the user handoff/login moment, interact with the login screen.
- Observe that the page can show an offline state.
Actual result
The in-app browser displays a site/app offline modal:
You are offline. Your changes will be saved when you are back online.
This blocks or disrupts the login handoff. The user reports this happens repeatedly at moments when they need to log in manually after Codex has opened the browser and paused.
Expected result
The in-app browser should keep pages online and stable while Codex waits for the user to complete login manually. After the user logs in, Codex should be able to resume work on the authenticated page.
Environment
- Product: Codex desktop app with in-app browser

A screenshot is available locally, but it contains private login-screen information, so I am not attaching it publicly without redaction. The visible error text is the offline modal quoted above.
