When using Roundproxies datacenter proxies, you may run into errors from the proxy network or the target site. The tables below summarize the most common ones, what they mean, and how to fix them.
Authentication Errors
| Error | Meaning | Fix |
|---|
407 Proxy Authentication Required | Credentials missing, malformed, or incorrect. | Verify credentials in the dashboard. If using IP whitelisting, confirm your current IP is added. |
401 Unauthorized | Account recognized but request not allowed. | Confirm your subscription is active, not over quota, and that your plan includes the requested datacenter pool. |
Connection Errors
| Error | Meaning | Fix |
|---|
Connection Timed Out | The proxy didn’t respond in time. | Retry the request and use a closer datacenter region if available. |
Connection Refused / Reset | Connection rejected or dropped mid-request. | Check firewall/outbound rules and confirm you’re using the correct port for the endpoint. |
IP / Pool Errors
| Error | Meaning | Fix |
|---|
IP Banned by Target | The datacenter IP is recognized and blocked by the destination. | Rotate to a new IP from the pool or switch to Residential Proxies for stricter targets. |
Dedicated IP Unavailable | Your dedicated IP is offline or being replaced. | Wait a few minutes and retry — replacements happen automatically. Contact support if it persists. |
HTTP Status Errors From the Target Site
These come from the destination website, not the proxy itself.
| Error | Meaning | Fix |
|---|
403 Forbidden | Site is blocking the request. | Rotate IPs more aggressively; consider residential proxies for sensitive targets. |
429 Too Many Requests | Site is rate-limiting your requests. | Slow the request rate and rotate IPs more often. |
5xx | Server-side error on the target site. | Retry with exponential backoff; try a different IP from the pool. |
Quota / Billing Errors
| Error | Meaning | Fix |
|---|
Bandwidth or Request Limit Reached | Plan quota exhausted. | Upgrade your plan or wait for the next billing cycle. Monitor usage in the dashboard. |
