Additional Information

Country, State, City Mapping
We use the MaxMind GeoIP2 database to assign our exit nodes cc, st, and city values. This database is updated weekly.
Some other public IP databases may show different locations. In cases where there can not be any location mismatches, please double-check if the location of the assigned proxy is the same on the IP database used by the target website.
Response codes

Response
Description
400 Bad Request
A proxy server can return this error code if the request did not contain a host to connect to or if there was a generic error when parsing an HTTP request. Make sure you formed the request correctly, including the URL in the request, then try again.
407 Proxy Authentication Required
Request lacks proxy authentication information, or username or password is invalid. Include the Proxy-Authorization header in your request, ensure that your username and password are formed correctly, then try again.
500 Internal Server Error
Proxy server has encountered an internal error. Retry request at a later time.
502 Bad Gateway
A proxy server received an invalid response from the upstream server. Retry request.

Response Code 502 signifies that the IP assigned to your session ID is no longer available. If you encounter this error, there are two ways to work around it. The first is to wait for one minute as the system automatically assigns a new IP address to your session ID. Another approach is to switch to a new session ID (i.e., change the sessid parameter) – this way, you will receive a new IP address.
522 Timeout
A proxy server did not receive a response from the upstream server in time. Retry request.
525 No Exit Found
Custom HTTP status code - this means the proxy could not find an exit node that satisfies the request. Change request filter parameters or try again at a later time.
Backonnect Entry IPs
If you want to use your own backconnect entry node DNS name, you can point your subdomain/domain to our entry node. To do that, you need to add a DNS CNAME record with pr.oxylabs.io as the target. This is how such setup looks on Cloudflare DNS manager for entry subdomain:
