Error Handling - Roundproxies Docs

Errors come either from the proxy or from the site you requested. These are the most common ones and how to fix them.

Authentication Errors

Error	Meaning	Fix
`407 Proxy Authentication Required`	Credentials are missing or wrong.	Check your credentials in the dashboard. If you use IP whitelisting, make sure your current IP is on the list.
`401 Unauthorized`	Your account was recognized, but the request isn’t allowed.	Make sure your subscription is active, you are within your limits, and your plan includes these datacenter proxies.

Connection Errors

Error	Meaning	Fix
`Connection Timed Out`	The proxy didn’t respond in time.	Try again, and use a closer datacenter region if one is available.
`Connection Refused` or `Reset`	The connection was rejected or dropped.	Check your firewall and make sure you are using the right port.

IP Errors

Error	Meaning	Fix
`IP Banned by Target`	The site recognizes the datacenter IP and blocks it.	Switch to another IP from your list, or use Residential Proxies for stricter sites.
`Dedicated IP Unavailable`	Your IP is offline or being replaced.	Wait a few minutes and try again. Replacements happen automatically. Contact support if it continues.

Errors From the Site

These come from the website you requested, not from the proxy.

Error	Meaning	Fix
`403 Forbidden`	The site is blocking the request.	Switch IPs more often, or use residential proxies for sensitive sites.
`429 Too Many Requests`	The site is rate-limiting you.	Send fewer requests and switch IPs more often.
`5xx`	The site has a server error.	Try again with exponential backoff, or with a different IP.

Billing Errors

Error	Meaning	Fix
`Bandwidth or Request Limit Reached`	Your plan’s limit is used up.	Upgrade your plan or wait for the next billing period. You can check your usage in the dashboard.
