Explanation of Proxy Server IP

A proxy server, as the name suggests, acts as an intermediary between the client and the target server, it receives requests from the client and forwards them to the target server and forwards the response from the target server to the client. Therefore, the proxy server IP is the IP address that the client uses to connect to the proxy server.

Reasons for Proxy Server Connection Failure

1. Network problem: There is a problem with the network connection between the client and the proxy server, resulting in a failure to establish a connection.

"`ipipgothon
import requests

try.
response = requests.get('http://127.0.0.1:8888')
print(response.text)
except requests.exceptions.RequestException as e:.
print(e)
“`

2. Proxy Server Failure: The proxy server itself fails and cannot forward the client's request normally or cannot get the response from the target server.

"`ipipgothon
import requests

proxies = {
'http': 'http://proxy.example.com:8888',
'https': 'https://proxy.example.com:8888',
}

try.
response = requests.get('http://example.com', proxies=proxies)
print(response.text)
except requests.exceptions.RequestException as e:.
print(e)
“`

To summarize, proxy server IP connection failure may be caused by network problems or proxy server failure. In practice, you need to carefully investigate the root cause of the problem and take appropriate measures to solve it.
