The 466 Too Many Requests error occurs when you exceed the allowed thread limit for your account or subscription plan. This means you are making more concurrent connections or requests than your plan allows, which can overload the system and impact performance for both your application and our proxy network.

To resolve this issue, simply reduce the number of threads or concurrent connections you are using. By lowering the volume of simultaneous requests, you can stay within your allocated limits and avoid encountering this error in the future.

If you find that your current thread limit is not enough for your needs, consider upgrading to a plan that supports higher concurrency.
