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. See Authentication.
`401 Unauthorized`	Your account was recognized, but the request isn’t allowed.	Make sure your subscription is active and your plan includes these ISP proxies.

Connection Errors

Error	Meaning	Fix
`Connection Timed Out`	The proxy didn’t respond in time.	Try again. If one IP keeps timing out, replace it in the dashboard.
`Connection Refused` or `Reset`	The connection was rejected or dropped.	Check your firewall and use the port from your proxy list.

IP Errors

Error	Meaning	Fix
`IP Banned by Target`	The site has blocked your static IP.	Replace the IP in the dashboard. This happens less often than with datacenter IPs, but heavy use on one site can still cause it.
`Static 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.	Slow down, vary your requests, or spread the load over more IPs.
`429 Too Many Requests`	The site is rate-limiting your IP.	Send fewer requests. A static IP can’t rotate away from a rate limit.
`5xx`	The site has a server error.	Try again with exponential backoff.

Billing Errors

Error	Meaning	Fix
`Plan Expired`	Your ISP proxy plan has ended.	Renew it in the dashboard. Your IPs are kept for a short grace period before they are released.
