Grok Bot computer host service down since Oct 23: browser/screenshot blocked by "saved credential" error, Update does nothing

Where does the bug appear (feature/product)?

Grok Bot

Describe the Bug

Describe the Bug
Since Oct 23, 2026 at about 11:25 UTC (6:25 AM CT), every browser action and Screenshot on my bot’s computer fails with:

The box could not confirm that no saved credential is being filled into its browser, so this tool did not run.

Everything else still works: Shell, files, connectors and routines. Only the browser and desktop are blocked.

Steps to Reproduce

  1. Ask the bot to open any page (e.g. example.com) or take a screenshot.
  2. The tool is refused with the error above, every time, for about 4 days now.

Diagnostics (from the bot’s computer)

  • /tmp/sand-supervisor/status.json: hostRunning: false, hostVersion: 78042fa, gatewayDescriptorPresent: false
  • /tmp/sand-host.log: 0 bytes, last modified Oct 23 11:25 UTC
  • box-doctor (Oct 25): 11 checks, 0 failed. Chrome running; egress, clock, dbus and disk fine.

What I’ve Tried

  • Update Bot’s Computer on Oct 23: no effect. The Update row is no longer visible in my settings.
  • Emailed [email protected] Oct 25 at about 13:30 UTC: no reply yet.
  • Sent in-app feedback Oct 26.

This looks like the same issue as topics 175929 and 176355, where the fix was moving to a fresh computer.

Impact
All social posting, YouTube uploads and analytics across my 12 bots have been blocked for about 4 days.

I’m backing up my files to my own drive today and will confirm here once it’s done. Please move me to a fresh computer, keeping my bots, chats and routines. Thank you!

Steps to Reproduce

Just try to use any of my bots that require the computer.

Operating System

Windows 10/11

Hey there!

You should have a working box again. Can you check?
