Common socks5 proxy error codes
by louise

Socks5 proxy is a network protocol that allows users to access Internet resources through a proxy server. It can help users hide their real IP addresses and protect their privacy and security. However, you may also encounter some error codes when using socks5 proxy. This article will introduce common socks5 proxy error codes and analyze their causes and solutions.


1. 0x01:General SOCKS server failure


This error code indicates that a general error occurred in the socks5 server, resulting in the inability to complete the user's request. Possible causes include server failure, network connection issues, or server configuration errors. The solution is to check the server status, make sure the network connection is normal, and check whether the server configuration is correct.


2. 0x02:Connection not allowed by ruleset


This error code indicates that the socks5 server rejected the user's connection request because the server's ruleset does not allow the connection. Possible reasons include the IP address port being restricted or the user identity authentication failing. 


The solution is to contact the server administrator to confirm whether your IP address is restricted and check whether the authentication information is correct.


3. 0x03:Network unreachable


This error code indicates that the socks5 server cannot access the target host requested by the user because the target host is unreachable. Possible causes include target host failure, network failure, or incorrect target host address. 


The solution is to check the target host status, make sure the network connection is normal, and check whether the target host address is correct.


4. 0x04:Host unreachable


This error code indicates that the socks5 server cannot access the target host requested by the user because the target host is unreachable. Similar to the previous error code, but possible causes are different, including target host firewall blocking, incorrect routing settings, or network congestion. 


The solution is to check the target host firewall settings, check that the routing settings are correct, and try to connect during a period of less network congestion.


5. 0x05:Connection refused


This error code indicates that the socks5 server rejected the user's connection request because the server port is not open or the server is fully loaded. The solution is to check the server port settings to make sure the port is open and try to connect during a time when the server load is lighter.


6. 0x06:TTL expired


This error code indicates that the socks5 server cannot complete the user's request because the packet's time-to-live has expired. Possible causes include network failure, incorrect routing settings, or packets being dropped by intermediate nodes. The solution is to check the network connection and routing settings to ensure that the packets are transmitted properly.


7. 0x07: Command not supported


This error code indicates that the socks5 server does not support the command sent by the user, resulting in the inability to complete the user's request. Possible reasons include commands not supported by the server, protocol mismatch, or version incompatibility. 


The solution is to check the commands and protocols supported by the server, make sure the versions are compatible, and try using other commands to send the request.


8. 0x08:Address type not supported


This error code indicates that the socks5 server does not support the address type requested by the user, resulting in the inability to complete the user's request. Possible reasons include an address type that is not supported by the server, a protocol mismatch, or a version incompatibility. 


The workaround is to check the address types and protocols supported by the server, make sure the versions are compatible, and try using a different address type to send the request.


9. 0x09:Unknown error


This error code indicates that an unknown error occurred in the socks5 server, resulting in the inability to complete the user's request. Possible causes include server failure, network connection issues, or server configuration errors. The solution is to contact the server administrator to confirm that the server status and configuration are correct.


Summarize


The above are common socks5 proxy error codes and their solutions. When using socks5 proxy, you may encounter a variety of errors, but most of them can be solved by checking the network connection, confirming the server configuration and contacting the server administrator. 


At the same time, users can also learn more about socks5 agents by reading relevant documents and forum posts to better solve problems.
