Many users need to use proxy IP to access some websites to meet business needs. When using proxy IP, the website may be inaccessible. The setting methods are different for different application scenarios. The following are common reasons why proxy IP cannot be accessed:
1. Permission failure
High-quality proxy IPs need to be authorized on the whitelist before use. If the authorization whitelist fails, the website will not be accessible.
2. The anonymity of the proxy IP is not enough
There are many types of proxy IPs, including open and transparent proxies. Generally, these proxies are not anonymous enough and can be easily detected by the target site and thus restricted. Choosing a highly anonymous proxy IP can hide the local real IP and will not be easily discovered.
3. Extracted IP is not used in time
The expiration time of the proxy IP is not counted from the time it is used, but from the time it is extracted from the API. If it is not used immediately, the website will not be accessible after the proxy IP expires.
4. Single proxy IP access
It is normal for proxy IP to be blocked. If the proxy IP is accessed too frequently, it will also be restricted. If the operator's proxy IP pool is small, many people may have used the same IP and were restricted before visiting a website.
