Troubleshooting: Can't create resources due to insufficient balance

Symptoms​

The Create button is greyed out (disabled), or the system shows a message such as:

"Insufficient balance to create this resource." "Estimated Cost exceeds available balance."

Cause​

The system compares Estimated Cost against Available Balance before allowing resource creation. The Create button is disabled when:

Estimated Cost ≥ Available Balance

Note: Available Balance ≠ Total wallet balance. Funds currently on hold (for running resources) are not counted as usable. For example:

Total walletOn HoldAvailable Balance
100,000đ30,000đ70,000đ

If Estimated Cost is 80,000đ → the Create button is disabled even though the total wallet has 100,000đ.

Solutions​

Solution 1: Top up your wallet​

The fastest way to proceed with your desired configuration.

  1. See how to top up your wallet to add funds.
  2. After a successful top-up, return to the resource creation form — the Create button will be enabled if the balance is now sufficient.

Solution 2: Choose a smaller configuration to reduce Estimated Cost​

If you want to create immediately without topping up:

  1. Reduce the Flavor (choose fewer vCPUs/RAM) → Estimated Cost decreases.
  2. Reduce the attached Storage Disk size or skip Storage Disk (you can add it later).
  3. Recheck Estimated Cost after adjusting.

Solution 3: Release holds from old resources​

Held funds are locked by running resources. If you have resources you no longer need, delete them to release the hold and increase Available Balance:

  1. View your Instance list → delete Instances you no longer need.
  2. View your Storage Disk list → delete disks not attached to any Instance (unattached).
  3. After deletion, the corresponding hold is released and added back to Available Balance.

💡 Tip: Go to Compute Engine → Storage disks to find disks not attached to any Instance.

Quick checklist​

QuestionAction
Is the total wallet sufficient?Check the On Hold amount — it may be consuming most of the balance
Are there old Instances/Disks you don't need?Delete them to release held funds
Can the configuration be smaller?Temporarily reduce Flavor or disk size
Do you need the resource immediately?Top up your wallet
