1. The protocols do not match. The conventional protocols are divided into HTTP protocol and SOCKS5.

The misunderstanding of the protocol leads to the failure of the agent, so we should pay attention to distinguish whether the crawler software, program and agent IP protocol are the same. If you buy crawler software or programs, you need to confirm the requirements of the agreement with the author in advance, and ask the manufacturer to test when purchasing agent IP.

2. The IP whitelist is incorrect. In order to ensure the quality and bandwidth of the proxy IP, agents will require that the IP whitelist of the proxy IP be bound to avoid stealing and scanning the proxy IP.

Therefore, we must ensure that the proxy server is extracted and used in the background, and the IP whitelist is added in the background to limit the extraction and use of proxy IP. In this way, if the extraction and use need to be deployed separately, you can ask the agent to increase the number of IP whitelists.
