➡️ Understanding Proxy Error Codes

When using Rayobyte Residential Proxies, you may encounter HTTP error codes that indicate an issue with your request. Don't worry! Most errors have simple fixes. Below, we’ll break down common errors, their causes, and how to resolve them so you can get back to scraping smoothly.


➡️ 403 Forbidden – What It Means & How to Fix It

✔ What Causes a 403 Error?

  • ✔ The website is blocking your proxy.
  • ✔ Incorrect authentication (wrong username/password).
  • ✔ Your IP isn’t whitelisted (if using IP authorization).

✔ How to Fix It

  • Double-check your proxy credentials – Go to your Rayobyte Dashboard and verify your username and password.
  • Using IP Authorization? – Ensure your IP is correctly whitelisted.
  • Rotate to a different proxy location – The website may have blocked your current IP.
  • Test your proxy – Try connecting to https://api.ipify.org to confirm it's working.

➡️ 429 Too Many Requests – Rate Limiting Explained

✔ What Causes a 429 Error?

  • ✔ The target website has detected too many requests from your proxy.
  • ✔ Your request rate is exceeding the allowed limit.

✔ How to Fix It

  • Slow down your requests – Add delays or randomized wait times between requests.
  • Use IP rotation – Avoid sending too many requests from the same IP.
  • Mimic human behavior – If using a headless browser, introduce random pauses between actions.

➡️ Using cURL to Test Rayobyte Proxies

cURL is a simple way to test if your proxy is working and check responses from websites.

✔ Basic cURL Command (Username/Password Authentication)

Run the following command to confirm that your proxy is functioning properly:

curl -x http://username123:[email protected]:8000 https://api.ipify.org

Expected Output: This should return the IP address of your proxy, confirming it's active.


✔ Testing Proxies with IP Whitelisting

If you're using IP authorization instead of username/password, remove authentication from the command:

curl -x http://la.residential.rayobyte.com:8000 https://api.ipify.org

Tip: If you get a 403 error, check that your IP is correctly whitelisted in your Rayobyte Dashboard.


✔ Verifying a Target Website Through Your Proxy

Want to check if your proxy can access a specific site? Use this command:

curl -x http://username123:[email protected]:8000 https://example.com
