OAuth login redirect via vanadium

[J0nnyMak0]

When navigating to Vanadium via an app for Oauth login, Vanadium fails to redirect back to the app with the OAuth keys.

Observed behavior:

ecobee app (auth.ecobee.com)

After login and password are entered and 2FA code is entered, a page with message "Not found." shows up.

Expected behavior:

Vanadium should redirect back to ecobee app

I'm observing the same thing. This seems to only have become an issue in the last couple months.

• Phone: Pixel 6A
• GrapheneOS Build Number: 2025062700
• Google Play Services: 25.18.33
• Google Play Store: 46.1.39-31
• GMSCompatConfig: 158
• Vanadium: 138.0.7204.63.0

Behavior:

• Installed Grok v0.5.25 app from Google Play store in Private Space (also tried using Aurora Store install of Grok in main side of phone).
• Tapped "Sign In with X"
• Vandium opens OAuth login page.
• I complete login in Vanadium browser.
• Vanadium redirects back the Grok app.
• Grok posts error: "Error. Please retry." and login does not work.

Same behavior with ChatGPT app (v 1.2025.175) when trying to use OpenAI login in private space.
