Why am I getting 1021 error?

The HTTP 1021 error is typically associated with security services like Cloudflare, and it means:

Access Denied – You are being rate-limited or blocked because your IP or request pattern violates the server's firewall rules.

Possible Reasons for a 1021 Error in RChilli or Integrated Systems

If you're encountering this error in the context of using RChilli’s API or portal, it could be due to:

1. API Rate Limits Exceeded
   You've sent too many requests in a short time. RChilli enforces API usage limits per your plan, and crossing that threshold triggers this error.

2. Invalid or Suspicious IP/Geo Access
   If you're accessing the RChilli services from an unrecognized or restricted region/IP, the firewall might block the connection.

3. Misconfigured Headers or API Keys
   If the request contains missing or malformed headers (e.g., userkey, version, subuserid), the security service may block it as a suspicious request.

4. Server Selection Conflict
   If your RChilli account is configured for a specific region (like US or EU) and you're calling an endpoint from another region unintentionally, this could lead to a denial of service.

Recommended Fixes

Here’s what you can do:

✅ Step 1: Check Your API Usage

• Log in to My Account.

• Go to the Integration or My Plans tab.

• Review your parsing credits and expiration dates. If the limit is hit, your key will stop functioning and might return errors like 1021.

✅ Step 2: Confirm Correct Server Region

Make sure you're calling the API endpoint corresponding to your configured region. If you're unsure:

• Refer to: Server Location Configuration Guide.

• Or contact support to verify or change your server configuration.

✅ Step 3: Validate Your API Request

Ensure your request includes:

• A valid userkey

• The correct version (e.g., 8.0.0)

• A valid subuserid

• Properly formatted headers (Content-Type: application/json)

✅ Step 4: Wait or Retry Later

If it's a rate-limiting issue:

• Wait for 5–10 minutes before retrying.

• Implement retry logic with exponential backoff in your API client.
