Quicknode provides Error Logs for your RPC endpoints. Easily identify and resolve issues by viewing detailed error information directly from your dashboard.

HTTP Error Codes

Let's look at the common HTTP Error Codes you can encounter, what they mean and what you can do to prevent them.

400Bad Request

Incorrect HTTP Request type (e.g. using GET instead of POST) or Invalid Characters

401Unauthorized

This can happen when one or multiple security requirements are not met such as incorrect Token Auth, IP not in the whitelist, invalid JWT, etc.

403Forbidden

Endpoint Disabled (One of the reasons for this could be a past due payment)

403Forbidden - custom trace not found

Custom trace code not whitelisted (Submit a ticket to go through the approval process)

404Not Found

Incorrect URL or Incorrect method

413Content Too Large

Body of the request is too large

413Request Entity Too Large

eth_getLogs and eth_newFilter are limited to a 10,000 blocks range. We enforce a limit of 10,000 block ranges when requesting logs and events.

429Too Many Requests

The requests per second (RPS) of your requests are higher than your plan allows. Learn more about the 429 errors in our support documentation.

500Internal Server Error

Endpoint Logs

Quicknode provides logs for your RPC endpoints to help you diagnose issues. You can view logs directly in your Quicknode dashboard by navigating to:

1. Endpoints in the sidebar
2. Selecting your endpoint
3. Opening the Logs tab

You can filter logs by time window, response type, method, and network.

What Gets Logged

Endpoint Requests
Requests made to your endpoint, including the HTTP status, request method, RPC method or path, and timestamp.

Error Details
When available, failed requests include error details such as RPC error codes, request and response bodies, and links to related documentation.

Logging Limitations

Log availability can vary by method, response type, network, and plan. To maintain optimal endpoint performance, logging operates on a best-effort basis. Some logs may be dropped during high-traffic periods to preserve low latency.

Retention and Access

Build and Scale plans include dashboard access with standard log retention. Enterprise plans provide extended retention periods and programmatic API access for log retrieval.
