Running into error codes or functionality issues with OpenClaw can be frustrating, especially when subscription payments fail, API keys stop working, or your account suddenly gets locked. This article breaks down several common error types with detailed repair steps to help you restore normal use of the tool quickly.
Subscription Payment Errors: Card Declines and Amount Issues
The most common errors when subscribing to OpenClaw are "Payment declined" or "Invalid amount." These typically occur because your issuing bank has restricted cross-border payments, or your card balance is insufficient. Start by checking whether your bank card has overseas card-not-present transactions enabled, and confirm that the billing address matches the one registered with your card.
If the error code is "400" with a message like "invalid_card," it may be due to an incorrect card number or CVC code. Some virtual credit cards are also blocked by OpenClaw's system due to higher risk-control levels. In this case, try using a physical Visa or Mastercard, or contact your bank to request a temporary increase in the single-transaction limit.
API Call Failures: Key and Rate Limit Issues
When calling OpenClaw's API, "401 Unauthorized" or "429 Too Many Requests" are typical errors. The former means your API key has expired or is not correctly written into the request header. Log into the dashboard, generate a new key, and update it in your code. The latter indicates your account has hit the concurrency limit—wait 60 seconds and retry, or upgrade your subscription to increase the rate quota.
