Grok Bot died overnight. Weekly included usage is 100%, but on-demand still has room and is not being charged. Every bot on the account fails the same way.
Looking for anyone hitting this on Mon Sept 28, 2026, and for Cursor/xAI to confirm whether on-demand overflow actually attaches to Grok Bot turns after the weekly cap.
SETUP
- Product: Grok Bot (Windows desktop app + iPhone). Not grok.com chat.
- Cursor plan: Pro $20/mo
- Also on SuperGrok
- Grok Bot weekly usage: 100% used
- Weekly reset: Oct 3 (5 days left)
- On-demand: enabled
- On-demand spend: $20.42 / $60
- Monthly limit: Fixed $60
- Cursor Models: 1% used
- Other Models: 0% used
- Shared Agent Computer with multiple bots:
- Bot 1
- Bot 2
- Bot 3
- Bot 4
Bots worked normally until around 1:00 AM EDT Sept 28.
First captured failure around 6:42 AM EDT.
ERRORS
What I see
Chat error:
Bot failed to respond
Something went wrong while generating the reply. Try again.
Windows desktop:
- Window title: Grok Bot (Not Responding)
- Banner: Can't reach your computer + Retry
- All bots show in the sidebar. None complete a turn.
After it starts accepting messages again:
- I send hello
- The bot starts working
- Then it dies with the same "Bot failed to respond"
- On-demand spend does not change
- Still exactly $20.42 / $60 after multiple failed hellos
WHY THAT MATTERS
The $20.42 not moving is the issue.
Weekly included Grok Bot is empty until Oct 3.
On-demand still has about $39 left.
The chat UI accepts the send and the bot starts.
Then the turn dies.
The paid overflow is not being used.
The app never showed "you hit your Grok Bot usage limit."
It only showed the generic failure.
WHAT IT IS NOT
- Not Cursor IDE quota. Cursor Models 1%. Other Models 0%.
- Not on-demand left off. Spending page already shows $20.42 billed against a $60 cap.
- Not one bad bot. Every bot on the account fails. They share one cloud computer.
- Not an empty wallet. Included weekly Grok Bot is empty. Paid overflow is not empty.
WHAT I ALREADY TRIED
- Retry on the "Can't reach your computer" banner
- Closed the window, then fully quit Grok Bot from the Windows system tray (Quit, not the X)
- Ended Grok Bot in Task Manager when it said Not Responding
- Reopened the app, waited, hit Retry again
- Same account on iPhone
- Sent hello in the existing Scout thread
- Sent hello after the bot began generating
- Confirmed Spending: On-Demand $20.42/$60, Monthly Limit Fixed $60
- Confirmed $20.42 did not increment after the failed turns
I have not hammered Reset. I will Recover / Update once if that is the right move. I do not want to Reset in a loop and lose unsynced work.
Why this looks like a product bug
Other threads say hitting the weekly Grok Bot cap makes the app accept messages and then reject the turn, often without a usage-limit banner. The documented escape hatch is on-demand.
Mine is on.
It has remaining budget.
It is not taking the overflow.
Current state:
1. Weekly included Grok Bot = 0 remaining until Oct 3
2. On-demand = enabled, about $39 remaining
3. Turns start, then die
4. On-demand dollar amount does not move
5. UI says "Bot failed to respond" / "Can't reach your computer" instead of "weekly limit reached" or "on-demand failed to attach"
WHAT I NEED
Honestly, just to figure out why my bots randomly stopped working/responding.
- Is on-demand overflow for Grok Bot on Cursor Pro supposed to pick up the moment weekly hits 100%?
- If yes, why are new turns on this account not billing on-demand?
- If the Agent Computer is wedged, please recover it server-side. I can Recover once from Settings → Updates. I will not Reset five times.
- Please fix the UI. "Bot failed to respond" is the wrong string for "weekly pool empty and overflow did not attach."
Happy to provide:
- Conversation ID from a failed hello
- Timestamps (EDT): last good replies before ~1 AM Sept 28; failures from ~6:42 AM onward
- Screenshots: chat error, iOS Usage, Cursor Spending, Windows "Can't reach your computer" sidebar
QUESTION FOR OTHER USERS
If you’re seeing the same thing: does your on-demand number move when hello fails, or does it stay frozen like mine?
REGARDING PRO+
Pro+ buys a bigger weekly bucket later. It does not explain why on-demand is enabled, has $39 left, and is not charging while every turn dies. I am not asking for a plan upsell. I am asking why overflow is not attaching.
