Troubleshooting
Quick checks for sign-in, deposits, coupons, rentals, SSH keys, and pool connections.
| Issue | First checks |
|---|---|
| Cannot sign in | Allow Google OAuth pop-ups, retry in a private window, and confirm the correct Google account. |
| Deposit not visible | Verify the asset, network, transaction ID, and confirmation status. |
| Insufficient balance | Compare the available balance with the final crypto quote after any coupon. |
| Coupon rejected | Check every character, the expiry shown on the reward card, and whether it was already used. |
| SSH key rejected | Paste one complete OpenSSH public key line, not a private key or fingerprint. |
| Pool connection rejected | Confirm the pool URL is stratum+tcp://pool.mineharbor.com:3333, the Worker / Username is BTC_ADDRESS.WORKER_ID, and the password is x. |
