Fix a problem (renters)
API errors
Section titled “API errors”When something goes wrong, the API answers with an error code. Look for the code in the answer:
{ "error": { "message": "...", "type": "server_error", "code": "provider_offline" } }| Status | code | What it means | What to do |
|---|---|---|---|
| 401 | invalid_api_key | The key is missing, mistyped, replaced by New key, or the rental has ended. | Copy the key again. Check that the header is Authorization: Bearer gfk_…. If the rental ended, start a new one. |
| 400 | invalid_body | What you sent isn’t valid JSON. | Check your quotes and commas. The examples on Use your API key are a good starting point. |
| 503 | provider_offline | The provider’s machine is offline right now. | Wait a minute and try again. If it stays offline for 10 minutes, the rental ends by itself and you pay only until it went offline. |
| 503 | relay_unreachable | GPUFlow couldn’t reach the connection to the machine. | Try again in a moment. If it keeps happening, open a support ticket. |
| 502 | provider_error | The machine answered with nothing. | Try again. If it keeps happening, report the rental. |
| 503 | provider_unbound | Your key isn’t attached to a GPU. | Open a support ticket. |
“model … not found”: you asked for a model the machine doesn’t have. Run the /v1/models check from Use your API key and use that name.
Adding credits
Section titled “Adding credits”| Message | Fix |
|---|---|
| Confirm your email address before adding credits. | Open the email from GPUFlow and click the link. No email? Click Resend email on the yellow banner on your dashboard, and check your spam folder. |
| Enter an amount from $10 to $500. | Each top-up must be between $10 and $500. |
| Payment cancelled. Nothing was charged. | You left the Stripe page before paying. Try again. |
| You paid, but the credits haven’t shown up | Wait a minute and reload the page. Still nothing after 10 minutes? Open a support ticket. |
Starting a rental
Section titled “Starting a rental”| Message | Fix |
|---|---|
| Not enough credits: this needs … | Add credits, or rent for fewer hours. |
| This GPU’s machine is offline right now. | Pick another GPU, or click Notify When Online on its card to get an email when it’s back. |
| Choose … to … hours. | This GPU has its own minimum and maximum hours. Pick a number between them. |
| This is your own listing. | You can’t rent your own GPU. |
| Too many attempts. Try again in an hour. | Wait an hour. This limit protects accounts from runaway scripts. |
Still stuck?
Section titled “Still stuck?”Open a ticket at gpuflow.app/support. If it’s about one rental, use Report a problem next to it so we see which one. Include the error code, the time it happened and, if you can, the command or code you ran (without your API key).
